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 2-(pyridin-2-yl)thiazole-4-carboxylic acid (see Tetrahedron 2011, 67, 267) gave 326. 1H NMR (400 MHz, DMSO-d6) δ 9.91 (s, 1H), 8.70-8.65 (m, 1H), 8.50 (s, 1H), 8.35-8.30 (m, 1H), 8.04-7.97 (m, 1H), 7.87 (s, 1H), 7.59-7.53 (m, 1H), 4.94-4.88 (m, 1H), 4.84-4.67 (m, 1H), 4.48-4.34 (m, 1H), 4.24-4.07 (m, 1H), 3.80 (s, 3H), 3.60-3.47 (m, 1H), 2.17-2.09 (m, 1H), 1.96-1.78 (m, 3H).
