Procedure

tert-Butyl 7-[6-(2,6-difluoro-3,5-dimethoxyphenyl)-1H-pyrazolo[3,4-d]pyrimidin-3-yl]-3,4-dihydroisoquinoline-2(1H)-carboxylate (10.0 mg, 0.0191 mmol) in dichloromethane (0.10 mL) was treated with TFA (0.10 mL). The mixture was stirred at r.t. for 1 h. The volatiles were evaporated. The residue was dissolved in acetonitrile (0.5 mL) and N,N-diisopropylethylamine (30.0 μL). To the mixture was added methanesulfonyl chloride (2.0 μL, 0.026 mmol). The mixture was stirred at r.t. for 30 min, and then diluted with methanol, and purified by RP-HPLC (pH=10) to afford the desired product. LCMS (M+H)+=502.1.
