Procedure

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