Reaction Steps

4-Flurobenzoyl chloride (6.630-, 0.056 mmol) was added to a solution of tert-butyl(4-amino-2-(4-bromo-2-methyl-2H-pyrazol-3-yl)phenoxy)-2-methylpropan-2-ylcarbamate (0.25 mL of a 0.2M solution in dichloromethane, 0.050 mmol) and N,N-diisopropylethylamine (13.1 μL, 0.075 mmol) in dichloromethane (0.5 mL) and the reaction vessel was agitated on a mechanical shaker overnight. TFA (0.25 mL) was added, and the reaction vessel was shaken for another 30 min. The solvent was evaporated in vacuo, and the crude product was purified by RP-HPLC and lyophilized to give the title compound as a TFA-salt (26 mg, 92%). LCMS m/z (%)=463.2 (M+H 81Br 43%), 461.2 (M+H 79Br 43%). 1H NMR (400 MHz, DMSO-d6) δ ppm 1.09 (s, 3H), 1.11 (s, 3H), 3.60 (s, 3H), 3.76 (d, J=9.60 Hz, 1H), 3.92 (d, J=9.85 Hz, 1H), 7.21 (d, J=9.09 Hz, 1H), 7.27-7.36 (m, 2H), 7.60 (s, 1H), 7.62 (d, J=2.53 Hz, 1H), 7.86 (s, 3H), 7.87 (dd, J=9.09, 2.53 Hz, 1H), 7.93-8.00 (m, 2H), 10.30 (s, 1H).
