Reaction Steps

The reaction mixture of (S)-2-tert-butoxy-2-(7-(4-chlorophenyl)-5-methyl-2-(3-(1-methyl-1H-indazol-5-yl)phenyl)benzo[d]thiazol-6-yl)ethyl pivalate (10 mg, 0.015 mmol), 2N NaOH (150 μL) in THF/MeOH (1:1, 1 mL) was heated at 40° C. After reaction finished, the reaction mixture was diluted by EtOAc, washed by sat. NaHCO3, extracted by EtOAc, the organic phase was dried over MgSO4, filtered, concentrated down and purified by silica gel column, eluting by 0-100% EtOAc in hexanes to give the product. LCMS-ESI+: calc'd for C34H32ClN3O2S: 582.2 (M+H+); Found: 582.2 (M+H+).
