Reaction Steps

Following the procedure for Example 101, starting with Intermediate 20, tert-butyl 6-fluoro-1-(1-methyl-4-nitro-1H-pyrazol-5-yl)azepan-4-ylcarbamate and 5-(tert-butoxycarbonylamino)-2-(2,6-difluorophenyl)thiazole-4-carboxylic acid from Example 25 gave, after silica gel column chromatography (0-10% MeOH/DCM, 1% 7 N ammonia in MeOH), a white solid (273 mg, 19% over three steps). Compound 126 was obtained as a single enantiomer from SFC chiral separation of the racemic mixture. 1H NMR (400 MHz, CDCl3) δ 8.52 (s, 1H), 7.80 (s, 1H), 7.37-7.28 (m, 2H), 7.08-6.98 (m, 3H), 6.13 (s, 2H), 4.83-4.78 and 4.72-4.68 (2 m, 1H), 3.79-3.72 (m, 3H), 3.54-3.30 (m, 3H), 3.24-3.12 (m, 2H), 2.31-2.22 (m, 1H), 2.18-2.07 (m, 1H), 1.93-1.76 (m, 2H). LCMS (ES+) m/z 466 (M+1).
