Reaction Steps

To a mixture of 3-(1-Acetyl-4-oxo-piperidine-3-carbonyl)-benzonitrile (2a) (8 g, 29.6 mmol) in ethanol (26 ml) at 10° C. hydrazine hydrate (4.44 g, 88.8 mmol) was added slowly within 5 min. The mixture was stirred 3 h and allowed to warm to room temperature overnight. The mixture was concentrated to ¼ of its volume until a precipitate formed. The suspension was stirred for 2 h, cooled down and filtrated.
