Reaction Steps

Following the procedure for Example 111 starting from tert-butyl ((3S,4R,7S)-3-fluoro-7-(1-methyl-4-nitro-1H-pyrazol-5-yl)oxepan-4-yl)carbamate (Intermediate 80), and replacing 5-((tert-butoxycarbonyl)amino)-2-(2,6-difluorophenyl)thiazole-4-carboxylic acid with 5-((tert-butoxycarbonyl)amino)-2-(2,3-difluorophenyl)thiazole-4-carboxylic acid (Example 25) gave 324. 1H NMR (400 MHz, DMSO-d6) δ 9.34 (s, 1H), 8.07 (dd, J=8.3, 6.5 Hz, 1H), 7.87 (s, 1H), 7.52 (s, 2H), 7.48-7.38 (m, 1H), 7.31-7.22 (m, 1H), 4.87-4.80 (m, 1H), 4.56-4.38 (m, 1H), 4.36-4.23 (m, 1H), 4.16-3.99 (m, 1H), 3.76 (s, 3H), 2.09-2.01 (m, 1H), 1.87-1.66 (m, 5H).
