Procedure

The reaction mixture of (S)-ethyl 2-tert-butoxy-2-(7-(4-chlorophenyl)-5-methyl-2-(3-(pyrimidin-5-yl)phenyl)benzo[d]thiazol-6-yl)acetate (9 mg, 0.0157 mmol), excess NaOH, in MeOH/THF (1:1, 2 mL) was heated at 45° C. overnight. After reaction finished, the solvent was removed and the residue was dissolved in MeOH and purified by reverse phase HPLC, eluting by 0-100% acetonitrile in H2O with 0.1% TFA to give the product. LCMS-ESI+: calc'd for C30H26ClN3O3S: 544.1 (M+H+); Found: 544.2 (M+H+). 1H NMR (400 MHz, CD3OD): δ 9.18 (s, 1H), 9.16 (s, 2H), 8.40 (s, 1H), 8.12 (d, J=4 Hz, 1H), 7.91-7.88 (m, 2H), 7.71-7.67 (m, 2H), 7.60-7.58 (m, 3H), 5.26 (s, 1H), 2.62 (s, 3H), 0.97 (s, 9H).
