Procedure

A solution of methyl(5R)-3-[4-(2,5-dihydro-1H-pyrrol-1-yl)-3,5-difluorophenyl]-2-oxo-5-oxazolidine-5-carboxylate (Step 4, 0.09 g, 0.28 mmol) in 2.0M ammonia in MeOH (2.8 mL) is heated to 55° C. for 4 h. The reaction mixture is cooled, concentrated and the residue purified by pTLC (5% MeOH/CH2Cl2) to give the title compound (50 mg, 58%); MS for C14H13F2N3O3MS m/z 310.5 (M+H)+; 1H NMR (300 MHz, d6-DMSO): δ 3.93-3.98 (m, 1H), 4.17-4.25 (m, 5H), 4.97-5.02 (m, 1H), 5.93 (s, 2H), 7.27 (d, 2H), 7.61 (s, 1H), 7.85 (s, 1H).
