Procedure
A solution of 1-(4-methoxyphenyl)cyclopropanecarbonyl chloride (21.1 mmol) in anhydrous dichloromethane (20 mL) was slowly added to a cooled solution (0° C.) of 6-chloro-5-methylpyridin-2-amine (21.2 mmol) in dichloromethane (50 mL) and Et3N (14.1 mL, 101 mmol). The reaction mixture was stirred at room temperature for 2 hours. The resulting mixture was diluted with dichloromethane and washed with water (1×30 mL), 1N NaOH (2×30 mL), 1N HCl (1×30 mL), saturated aqueous NaHCO3 (1×30 mL) and brine (1×30 mL). The organic layer was dried over anhydrous Na2SO4 and evaporated under reduced pressure. The crude product was purified by column chromatography on silica gel (0-30% ethyl acetate in hexane) to yield N-(6-chloro-5-methylpyridin-2-yl)-1-(4-methoxyphenyl)cyclopropanecarboxamide (4.0 g, 63%) as a white solid.
