Procedure

In a four neck round bottom flask charged with 4-{4-[(5S)-5-(aminomethyl)-2-oxo-1,3-oxazolidin-3-yl]phenyl}morpholin-3-one free base (50 g) toluene (350 ml) and formic acid (21.63 g). Reaction mass then heated azeotropically to 110-120° C. employing dean-stark apparatus for 3 to 4 h. (water removed azeotropically) Reaction mass is cooled to 25 to 30° C. Obtained solid is filtered off and washed by toluene.
