2-bromo-isonicotinamide (406.2 mg, 2.021 mmol) and N,N-dimethylformamide diethyl acetal (0.48 ml, 2.80 mmol) were combined and heated to 120° C. A short path distillation apparatus was used to collect the ethanol that was liberated during the reaction. The reaction mixture was a light orange solution that slowly turned darker until it had become a dark amber solution. After 1.5 hours, the reaction mixture was cooled to room temperature. The reaction mixture solidified upon cooling and was placed under high vacuum overnight to give the title compound (507.4 mg) as an off-white solid.
