실험 절차
Benzotriazol-1-yloxy-tris(dimethylamino)-phosphonium hexafluorophosphate (BOP) (0.845 g, 1.91 mmol) was added to a suspension of 5-(3,4-dichloro-phenyl)-7-trifluoromethyl-pyrazolo[1,5-a]pyrimidine-2-carboxylic acid (0.600 g, 1.59 mmol) and benzylamine (0.209 mL, 1.91 mmol) in tetrahydrofuran (25 ml) containing triethylamine (0.665 mL, 4.77 mmol). The reaction mixture was stirred overnight at room temperature, diluted with ethyl ether (25 mL) and washed with a saturated aqueous solution of sodium bicarbonate (50 mL). The organic layer was collected, concentrated under reduced pressure and the crude product was purified by column chromatography on silica gel to give 5-(3,4-dichloro-phenyl)-7-trifluoromethyl-pyrazolo[1,5-a]pyrimidine-2-carboxylic acid benzylamide (0.665 g, 89%).
