Procedure
To a stirred solution of hydrochloride salt of N-{3-[4-(3-aza-bicyclo[3.1.0]hex-1-yl)-phenyl]-2-oxo-oxazolidin-5(S)-yl-methyl}-acetamide (Intermediate IV) (210 mg, 0.6 mmol), in dichloroethane (25 mL), were added 3-pyridinecarboxaldehyde (0.06 mL, 0.6 mmol), triethyl amine (0.17 mL, 1.2 mmol) and sodium triacetoxyborohydride (254 mg, 1.2 mmol) at 0° C. under nitrogen atmosphere. The reaction mixture was stirred at r.t. and progress of the reaction was monitored by TLC. On completion, the reaction mixture was quenched by adding saturated aq. NaHCO3 solution (20 mL) and product was extracted with DCM (3×25 mL). The organic layer was washed with water (25 mL), brine (25 mL), dried over anhydrous sodium sulphate and concentrated in vacuo. The residue was purified by column chromatography (silica gel, 0.5:9.5 MeOH:CHCl3) to provide the title compound (98 mg, 40%) as off white solid.
