Reaction Steps

(S)-ethyl 2-tert-butoxy-2-(7-(4-chlorophenyl)-5-methyl-2-(2-methyl-1-oxoisoindolin-5-yl)benzo[d]thiazol-6-yl)acetate (36 mg, 0.064 mmol) dissolved in THF/MeOH (1.25 mL/1.25 mL) and 2N NaOH (0.160 mL) was heated at 50° C. for 2 h and the crude was purified by reverse phase HPLC, eluting by 0-100% acetonitrile in H2O with 0.1% TFA to give the title compound. LCMS-ESI+: calc'd for C29H27ClN2O4S: 535.1 (M+H+); found: 535.2 (M+H+). 1H NMR (400 MHz, DMSO-d6): δ 8.22 (s, 1H), 8.08 (d, J=8.0 Hz, 1H), 7.87 (s, 1H), 7.70 (d, J=8.0 Hz, 1H), 7.65-7.51 (m, 4H), 5.03 (s, 1H), 4.46 (s, 2H), 3.03 (s, 3H), 2.48 (s, 3H), 0.83 (s, 9H).
