Versuchsvorschrift

A solution of methyl 5-bromo-2-(3-ethylureido)isonicotinate (Intermediate 1, 56.22 g, 186.0 mmol) in 7N ammonia in methanol (1 L) was allowed to stir at room temperature in a sealed flask for 1½ d. The precipitate that formed was collected by filtration, rinsed with acetonitrile (500 mL), and then dried on the high vacuum pump overnight, yielding 50.8 g of a solid (95.1%).
