Reaction Steps

Following the procedures from Example 140, (R)-benzyl 1-(4-amino-1-methyl-1H-pyrazol-5-yl)azepan-4-ylcarbamate from Example 16 and 5-(tert-butoxycarbonylamino)-2-(2,3-difluorophenyl)thiazole-4-carboxylic acid from Example 42 were converted to 377. 1H NMR (400 MHz, DMSO) δ 8.92 (br, 1H), 8.06 (t, J=7.2 Hz, 1H), 7.62-7.39 (m, 4H), 7.34 (dd, J=13.1, 7.8 Hz, 1H), 3.66 (s, 4H), 3.20-3.01 (m, 5H), 1.92-1.76 (m, 3H), 1.71-1.47 (m, 3H). MS (ESI) m/z: 448.2 [M+H+].
