1-(溴甲基)-4-氯-2-甲基磺酰苯

反应条件: temp:80.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: A mixture of piperazine-1-carboxylic acid (7-methoxy-thiazolo[5,4-d]pyrimidin-2-yl)-amide hydrochloride (as prepared in Example 1, 625 mg, 1.70 mmol) in N,N-dimethylformamide (5 mL) was treated with N,N-diisopropylethylamine (660 mg, 5.10 mmol) followed by 1-(bromomethyl)-4-chloro-2-(methylsulfonyl)-benzene (530 mg, 1.87 mmol). The reaction mixture was allowed to stir at 80° C. for 3 h. At this time, the reaction was poured into water. The aqueous layer was extracted with ethyl acetate. The organics were washed with a saturated aqueous sodium chloride solution, dried over magnesium sulfate, filtered, and concentrated in vacuo. Flash chromatography (Merck Silica gel 60, 230-400 mesh, 80/20 hexanes/ethyl acetate) afforded 4-(4-chloro-2-methanesulfonyl-benzyl)-piperazine-1-carboxylic acid (7-methoxy-thiazolo[5,4-d]pyrimidin-2-yl)-amide (580 mg, 69%) as an off-white solid; LRMS for C19H21ClN6O4S2 (M+H)+ at m/z=496. The NMR spectrum obtained on the sample is compatible with its structure. The aqueous layer was extracted with ethyl acetate The organics were washed with a saturated aqueous sodium chloride solution dried over magnesium sulfate filtered concentrated in vacuo

反应条件: temp:100.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: To a solution of 2-amino-5-chloronicotinamide (0.15 g) in N,N-dimethylformamide (3 ml) was added 1-(bromomethyl)-4-chloro-2-(methylsulfonyl)benzene (0.37 g), and the mixture was stirred at 100° C. for 14 hr. The reaction mixture was diluted with ethyl acetate. The precipitate was collected by filtration and washed with ethyl acetate. The obtained precipitate was recrystallized from methanol-ethyl acetate to give the title compound (50 mg). The precipitate was collected by filtration washed with ethyl acetate The obtained precipitate was recrystallized from methanol-ethyl acetate
