Reaction Steps

To a vial was dissolved (S)-ethyl 2-tert-butoxy-2-(7-(4-chlorophenyl)-5-methyl-2-(1-methyl-3-(pyridin-3-yl)-1H-indazol-5-yl)benzo[d]thiazol-6-yl)acetate (69 mg, 0.11 mmol) in THF (2 mL) and EtOH (1 mL). 1M NaOH (1 mL) was added, and the mixture was heated to 50° C. for 15 hours. The reaction was cooled to 23° C., and filtered (0.45 micron teflon syringe filter). The filtrate was purified by reverse phase HPLC, eluting with 5-100% acetonitrile in H2O with 0.1% TFA to give the desired product as a light yellow powder. LCMS-ESI+: calc'd for C33H30ClN4O3S: 597.1 (M+H+); Found: 597.2 (M+H+). 1H NMR (400 MHz, CD3OD) δ 9.32 (s, 1H), 8.89 (d, J=8.1 Hz, 1H), 8.72 (d, J=4.5 Hz, 1H), 8.66 (s, 1H), 8.09 (dd, J=8.9, 1.4 Hz, 1H), 7.95 (dd, J=7.9, 5.5 Hz, 1H), 7.79 (s, 1H), 7.76-7.67 (m, 2H), 7.63-7.52 (m, 3H), 5.26 (s, 1H), 4.17 (s, 3H), 2.61 (s, 3H), 0.98 (s, 9H).
