実験手順

A solution of 2,6-dichloronicotinoyl chloride (62.5 g), ethyl 3,3-dimethylaminoacrylate (58.8 g) and triethylamine (69 g) in toluene (600 mL) was stirred at 90° C. for 1 hour then cooled and concentrated. The concentrate was dissolved in dichloromethane (60 mL), diluted with diethyl ether, and filtered. The filtrate was concentrated, and the concentrate was crystallized from dichloromethane/diethyl ether/hexanes.
