Procedure

A solution of (5R)-3-(4-(1,2,5,6-tetrahydropyridin-4-yl)-3,5-difluorophenyl)-5-(1,2,3-triazol-1-ylmethyl)oxazolidin-2-one hydrochloride (650 mg, 1.64 mM) in dry dichloromethane (20 ml) at 0–4°, was treated with pyridine (648 mg, 8.2 mM) followed by dropwise addition of (4S)-2,2-dimethyl-1,3-dioxolane-4-carbonyl chloride (430 mg, 2.64 mM). The solution was allowed to warm to ambient temperature and stir for 1 hour. The reaction mixture was washed with water and brine, dried (sodium sulfate) and evaporated to a gum which crystallised readily on trituration with diethyl ether to give the title compound (788 mg).
