実験手順

To a solution of (S)-2-tert-butoxy-2-(7-(4-chlorophenyl)-5-methyl-2-(5-(1-methyl-1H-indazol-5-yl)pyridin-3-yl)benzo[d]thiazol-6-yl)ethyl pivalate from above reaction was added THF:MeOH (1:1, 2 mL) and 2M NaOH (0.5 mL) were added and reaction mixture was heated at 55° C. for 3 h. Reaction mixture was cooled to rt, diluted with ethyl acetate and washed with saturated ammonium chloride solution. The organic layer was dried (MgSO4), filtered, concentrated and purified by CombiFlash (EtOAC/Hex) to give (S)-2-tert-butoxy-2-(7-(4-chlorophenyl)-5-methyl-2-(5-(1-methyl-1H-indazol-5-yl)pyridin-3-yl)benzo[d]thiazol-6-yl)ethanol (15 mg). LCMS-ESI+: calc'd for C33H32ClN4O2S: 583.2 (M+H+); found: 583.3 (M+H+).
