Procedure

To a solution of compound (S)-2-tert-butoxy-2-(7-(4-chlorophenyl)-5-methyl-2-(1-methyl-1H-pyrazolo[3,4-b]pyridin-5-yl)benzo[d]thiazol-6-yl)ethyl pivalate (14 mg, 0.024 mmol) in THF (0.50 mL) and MeOH (0.50 mL) was added aqueous NaOH (0.10 mL of a 2 N solution). The reaction mixture was heated at 50° C. for 17 h, cooled, diluted with satd. aqueous NH4Cl and extracted with ethyl acetate. The organic layer was dried and concentrated to give the desired product which was used without any further purification. LCMS-ESI+: calc'd for C27H28ClN4O2S: 507.2 (M+H+); 507.2 (M+H+).
