Reaction Steps

2-(2-Trifluoromethyl-phenyl)-pyrido[2,3-d][1,3]oxazin-4-one (2.51 g) is stirred in 30% ammonium hydroxide (25 ml) at room temperature overnight. The resulting precipitate is filtered and rinsed with water and diethyl ether. The precipitate is dried under vacuum at 50 C overnight to give 2-(2-trifluoromethylbenzoylamino)-nicotinamide (850 mg, 33% yield)
