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 5-(tert-butoxycarbonylamino)-2-(2-fluorophenyl)thiazole-4-carboxylic acid (Example 7) gave 186 as the hydrochloride salt as a white solid (38 mg, 71%). 1H NMR (400 MHz, d6-DMSO) δ 9.47 (s, 1H), 8.60-8.40 (m, 3H), 8.19-8.13 (m, 1H), 7.71 (s, 1H), 7.49-7.35 (m, 3H), 5.40-5.23 (m, 1H), 4.87 (d, J=10.5 Hz, 1H), 4.28 (ddd, J=32.0, 14.5, 4.7 Hz, 1H), 4.07 (ddd, J=23.4, 14.5, 2.8 Hz, 1H), 3.80 (s, 3H), 3.78-3.60 (m, 1H), 2.19-1.82 (m, 4H). LCMS (ES+) m/z 449 (M+1). Alkyl NH2 not observed.
