Reaction Steps
6.2 g (23.2 mmol) 1-(4-benzyloxy-phenyl)-pyrrolidin-2-one is dissolved in 200 ml THF. 3 drops of acetic acid are added and the solution is hydrogenated for 5 hours at RT and normal pressure in presence of 0.62 g palladium 10% on charcoal. Filtration and concentration gives a semisolid material. Chromatography (silica gel, dichloromethane/methanol 95:5) yields 2.73 g (66%) of a brownish solid. MS: m/e=175.9 (M−H).
