반응 단계
2-aminopyridine in an amount of 200 mg (2.13 mmol) was dissolved in 5 mL of dichloromethane, following which 491 mg (2.55 mmol) of EDC-HCl, 311 mg (2.55 mmol) of DMAP and 187 μL (2.23 mmol, 290 mg) of chlorodifluoroacetic acid were added in this order and the mixture was stirred overnight. Following reaction completion, the reaction mixture was diluted with dichloromethane, washed with water and 1% hydrochloric acid, then dried over anhydrous magnesium sulfate, giving 105 mg of 2-chloro-2,2-difluoro-N-(pyridin-2(1H)-ylidene)acetamide (yield, 24%).
