Reaction Steps

A suspension of 31 g 4-{4-[(5S)-5-(acetylamino-methyl)-2-oxo-oxazolidin-3-yl]-2-fluorophenoxymethyl}-4-hydroxy-piperidine-1-carboxylic acid benzylester (MW: 515.54 60.13 mmol) and 2.5 g of palladium 10% on activated carbon in 310 ml methanol and 150 ml ethyl acetate was stirred under hydrogen for 4 hrs. The reaction was monitored by TLC (ethyl acetate). The reaction slurry was diluted with 300 ml methanol, warmed to 40° C., and the catalyst filtered off using a glass fibre filter paper. The filtrate was concentrated to 150 ml, diluted with 300 ml ethyl acetate and concentrated again to 200 ml. 200 ml of diethyl ether were added, and the suspension was cooled to 0° C. under stirring. The solid was collected and dried. Yield: 21.6-g, 94.3%. MS: 382.6 (M+H)+, Method ESI+.
