实验步骤: To a solution of 5-phenyl-1,3-thiazole-4-carboxylic acid (300 mg) in toluene (6 mL) were added dropwise TEA (672 μL) and DPPA (409 μL) at room temperature, followed by stirring at the same temperature for 20 minutes. Next, after stirring at 90° C. for 5 minutes, a mixture of 3-aminoquinuclidine dihydrochloride (407 mg) and DMF (2 mL) was added thereto, followed by heating under reflux for 1 hour. To the reaction liquid was added water, followed by extraction with EtOAc. The organic layer was washed with water and brine in this order, dried over MgSO4, and then concentrated under reduced pressure. The residue was purified by medium-pressure preparative liquid chromatography (YAMAZEN YFLC WPrep2XY, eluent; CHCl3:MeOH:28% aqueous ammonia=80:10:1) to obtain an oily substance. This was dissolved in EtOH, followed by addition of 10% HCl/MeOH at room temperature and concentration under reduced pressure. The residue obtained was added with EtOH and EtOAc, and left to stand, and the solid precipitated was collected by filtration, and washed with EtOAc to obtain 1-(1-azabicyclo[2.2.2]oct-3-yl)-3-(5-phenyl-1,3-thiazol-4-yl) urea hydrochloride (15 mg) as a white solid.

实验步骤: A solution of 3-aminoquinuclidine dihydrochloride (2.5 g, 0.0126 mole) in 25 ml of water was treated with approximately 5 g of KOH and the resultant slurry/solution taken to complete dryness on the rotary evaporator at 50°/35 mm. The dry residue was carefully extracted by repeated triturations with warm tetrahydrofuran until a total volume of 130 ml had been collected and dried over magnesium sulfate. This solution of 3-aminoquinuclidine base was treated with a solution of 2-methoxy-5-sulfamylbenzoyl chloride (2.92 g, 0.0117 mole) in 50 ml of dry tetrahydrofuran by dropwise addition under nitrogen. The resultant very turbid solution was refluxed gently for about 30 min, then freed of tetrahydrofuran by allowing it to evaporate. The residue was taken up in 90% ethanol containing a few drops of ethereal hydrogen chloride, filtered and chilled. The solid produced was then recrystallized again to yield 4.3 g (97%), m.p. 233°-234° C. NMR, MS, and IR were in support of the structure proposed. the resultant slurry/solution taken to complete dryness on the rotary evaporator at 50°/35 mm The dry residue was carefully extracted had been collected dried over magnesium sulfate The resultant very turbid solution was refluxed gently for about 30 min to evaporate filtered chilled The solid produced was then recrystallized again to yield 4.3 g (97%), m.p. 233°-234° C

实验步骤: To a solution of 3.82 g (0.0192 mole) of 3-amino quinuclidine dihydrochloride in about 25 ml of carbon dioxide-free water was added 8 g (0.025 mole) of barium hydroxide octahydrate. The mixture was warmed for 5 minutes and then dried to a powder on a rotary evaporator. While protecting from contamination with carbon dioxide in the atmosphere, the powder was extracted in sequence with hot benzene and a 1:1 mixture of benzene-methylene chloride solution. The combined extracts were dried over magnesium sulfate and the mixture filtered. To the filtrate with agitation was added dropwise a solution of 3.4 g (0.0171 mole) of 2-propoxybenzoyl chloride in 50 ml of methylene chloride. The mixture was warmed on a steam bath to evaporate about 75% of the methylene chloride. Ligroin (60-110) was added and the mixture solidified.

实验步骤: A mixture of 3-aminoquinuclidine dihydrochloride, 6.95 g, (0.0349), 2,4-dimethoxybenzoyl chloride, 700 g, (0.0349 mole), anhydrous sodium carbonate, 36.99 g, (0.349 mole), 175 ml water, and 175 ml chloroform was stirred rapidly to achieve good mixing of the 2 layers for 20 hrs. The chloroform layer was then separated, washed with water, dried over anhydrous magnesium sulfate, and concentrated to an impure oil. The oil was triturated twice with 20 ml portions of petroleum ether to remove some impurities. The oil was then dissolved in ether and filtered to remove a small amount of insoluble material. The filtrate was treated with ethereal hydrogen chloride and the resulting salt collected to yield 2.70 g (23.7% yield) white solid. The salt was recrystallized from ethanol-isopropyl ether. Further recrystallization from methanol-ethyl ether yielded a white solid, m.p. 211°-212° C.
