Reaction Steps

Following the procedure for Example 111 starting from tert-butyl ((3R,4R,7S)-3-fluoro-7-(1-methyl-4-nitro-1H-pyrazol-5-yl)oxepan-4-yl)carbamate (Intermediate 24), and replacing 5-((tert-butoxycarbonyl)amino)-2-(2,6-difluorophenyl)thiazole-4-carboxylic acid with 2-(2,6-difluorophenyl)thiazole-4-carboxylic acid (see US2012/225061) gave 319. 1H NMR (400 MHz, DMSO-d6) δ 10.02 (s, 1H), 8.63 (s, 1H), 7.86 (s, 1H), 7.74-7.59 (m, 1H), 7.38 (t, J=8.9 Hz, 2H), 5.03-4.81 (m, 2H), 4.19-3.88 (m, 2H), 3.75 (s, 2H), 2.24-2.10 (m, 1H), 1.93-1.81 (m, 1H), 1.82-1.70 (m, 1H), 1.65 (d, J=14.0 Hz, 1H).
