Versuchsvorschrift

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-trifluoromethyl-benzoylamino)-nicotinamide (850 mg, 33% yield)

Aufarbeitung

  1. filtrationThe resulting precipitate is filtered
  2. washrinsed with water and diethyl ether
  3. customThe precipitate is dried under vacuum at 50 C
