Procedure
A solution of 1.0 g of 5-nitronicotinamide and 2ml of 37% formalin in 3 ml of dimethylformamide was stirred at 100° C. for 2 hours. After cooling, ice-water was added and the mixture was extracted with ethyl acetate. The extract was chromatographed over silica gel and recrystallized from ethanol to give 0.6 g of the desired product. mp 145° - 146° C.
