Participants

Reaction Steps

(R)-1-[4-(3-Fluoro-benzyloxy)-phenyl]-5-oxo-pyrrolidine-3-carbonitrile (0.211 g, 0.001 mol) and hydroxylamine hydrochloride (0.047 g, 0.001 mol) were dissolved in ethanol (4 ml) and N,N-diisopropylethylamine (0.120 ml, 0.001 mol) was added. The reaction mixture was stirred under reflux for three hours. The reaction was cooled to room temperature, the solvent was evaporated and the residue extracted with dichloromethane and purified by column chromatography on silica gel using a 19:1-mixture of dichloromethane and methanol as the eluent to yield (0.220 g, 94% of theory) of a yellow oil. MS (m/e)=344.3(M+H)+.
