실험 절차

To a solution of 6-bromo-5-methoxypyridin-2-amine (510 mg, 2.5 mmol) and Et3N (690 μL, 4.9 mmol) in dichloromethane (10 mL) was added a solution of 1-(2,2-difluorobenzo[d][1,3]dioxol-5-yl)cyclopropanecarbonyl chloride (650 mg, 2.5 mmol) in dichloromethane (5 mL). The resulting reaction mixture was allowed to stir at room temperature for 18 hours. The reaction mixture was then washed with 1N HCl (1×20 mL) and saturated aqueous NaHCO3 (1×20 mL). The organics were dried over sodium sulfate and evaporated to yield the product (850 mg, 81%). ESI-MS m/z calc. 426.0, found 427.3 (M+1)+. Retention time 2.05 minutes.
