Reaction Steps

A mixture of tert-Butyl (R)-2-(2,6-difluorophenyl)-4-(1-methyl-5-(3-(trifluoromethyl)piperazin-1-yl)-1H-pyrazol-4-ylcarbamoyl)thiazol-5-ylcarbamate (80 mg, 0.126 mmol) in TFA (1 mL) and DCM (4 mL) was stirred at ambient temperature for 3 hours. The pH of the mixture was adjusted to about 8˜9 by addition of ammonia and concentrated under reduced pressure to give a residue. The residue was purified by preparative HPLC to afford 169 formic acid salt (40 mg, 73%) as white solid. 1H NMR (500 MHz, DMSO-d6) δ (ppm): 8.84 (s, 1H), 7.50-7.55 (m, 3H), 7.37 (s, 1H), 7.25-7.28 (m, 2H), 3.47 (s, 3H), 3.36-3.48 (m, 1H), 3.07-3.16 (m, 3H), 2.94-2.96 (m, 2H), 2.78-2.80 (m, 1H), 1.24 (s, 1H); MS (ESI) m/z=488.1 (M+1+).
