实验步骤: A mixture of 2-cyclopropylethylamine hydrochloride (73 mg, 0.60 mmol), 1-benzyloxycarbonylmethyl-3,5-dichloro-6-methylpyrazinone (164 mg, 0.50 mmol) and sodium hydrogen carbonate (101 mg, 1.20 mmol) in toluene (1 mL) and water (0.5 mL) was stirred at 80° C. for 3 h. The reaction was then cooled and partitioned between methylene chloride and 10% citric acid solution. The organic layer was dried (Na2SO4) and evaporated in vacuo to give the title compound as a crystalline solid: The reaction was then cooled partitioned between methylene chloride and 10% citric acid solution The organic layer was dried (Na2SO4) evaporated in vacuo

实验步骤: A stirred mixture of 4.4 g (0.027 mole) of 1,1'-carbonyldiimidazole and 2.9 g (0.027 mole) of (aminoethyl)cyclopropane hydrochloride in 50 ml of methylene chloride was treated with the dropwise addition of 2.73 g (0.027 mole) of triethylamine. The reaction was exothermic. The mixture was cooled while stirring for 1 hr, then 9.6 g (0.025 mole) of 3-[4-(trifluoromethyl)phenoxy]azetidine, 56.66% purity (contains diphenylmethane) was added all at once and stirring continued for 18 hr. The reaction mixture was concentrated on a rotary evaporator to give an amber residue. Trituration of this residue with 30/60 petroleum ether gave only an insoluble oil. The trituration step was repeated with 2×20 ml of 30/60 petroleum ether and the residue treated with water to yield a white solid. The solid was recrystallized from isopropyl ether to yield 4.8 g (61.8%) of white platelike crystals; after during at 80° C. under 0.5 mm Hg vacuum, m.p. 132°-133° C. The mixture was cooled stirring continued for 18 hr The reaction mixture was concentrated on a rotary evaporator to give an amber residue to yield a white solid The solid was recrystallized from isopropyl ether to yield 4.8 g (61.8%) of white platelike crystals during at 80° C.
