206 mg 4-[7-Chloro-2-(4-methoxy-benzyl)-1-oxo-1,2-dihydro-isoquinolin-6-ylsulfanyl]-piperidine-1-carboxylic acid tert-butyl ester (285) in 6 ml of dichloromethane were treated with 83 mg m-Chloroperbenzoic acid over 2 h. The mixture was diluted with dichloromethane and washed with sodium hydrogen carbonate solution and brine. After drying over sodium sulfate all volatiles were evaporated and the crude product purified by chromatography 2:1 (ethyl acetate/Heptane) to obtain 4-[7-Chloro-2-(4-methoxy-benzyl)-1-oxo-1,2-dihydro-isoquinoline-6-sulfinyl]-piperidine-1-carboxylic acid tert-butyl ester as an off white solid.
