Step I (6): Preparation of (4S,5R)-4-(3,5-difluorobenzyl)-5-((R)-piperidin-2-yl)oxazolidin-2-one. A solution of (R)-tert-butyl 2-((4S,5S)-4-(3,5-difluorobenzyl)-2-oxooxazolidin-5-yl)piperidine-1-carboxylate (Step I (5), 200 mg) in CH2Cl2 (4 mL) was treated with TFA (2 mL). This reaction mixture was stirred at rt for 1 h. The mixture was then concentrated in vacuo with addition of toluene. 1N HCl solution (50 mL) was added and the mixture was extracted with diethyl ether, neutralized with 50% aqueous NaOH to pH=12. The mixture was extracted with ethyl acetate (50 mL) twice. The combined organic layers were dried (Na2SO4), and concentrated in vacuo to give 132 mg of the title compound:
