A solution of 1-{(4S,5R)-5-[4-(6-chloromethyl -pyridin-3-yl)-phenyl]-4-fluoromethyl-2,2-dimethyl-oxazolidin-3-yl}-2,2-difluoro-ethanone (25 mg, 0.06 mmol) and 1-Methyl-1H-imidazol-2-ylamine (30 mg, 0.3 mmol) in dimethyl formamide (2 ml) is heated at 75° C. for 16 h. The reaction mixture is concentrated to dryness, dissolved in CH2Cl2 (1 ml) and treated with trifluoroacetic acid (0.5 ml) and water (0.1 ml). The mixture is shaken at ambient temperature for 2 hours and then concentrated to dryness. The crude product is purified by preparative HPLC to give the title compound (7 mg): 1H NMR (400 MHz, DMSO-d6) 2.50 (s, 3H), 3.51 (s, 2H), 4.24-4.36 (m, 1.5H), 4.37-4.46 (m, 0.5H), 4.51-4.59 (m, 0.5H), 4.63-4.71 (m, 0.5H), 4.87-4.92 (m, 1H), 5.31 (s, 2H), 6.22 (t, 1H), 7.05-7.10 (m, 2H), 7.40-7.52 (m, 3H), 7.66-7.74 (m, 2H), 8.09-8.16 (m, 1H), 8.86 (s, 1H), 9.63-9.69 (m, 1H). m/z M+H 434.
