Procedure

4-(1-acetyl-1,2,3,6-tetrahydropyridin-4-yl)-3-(1-(4-amino-3-(3-((tert-butyldimethylsilyl)oxy)-5-fluorophenyl)-1H-pyrazolo[3,4-d]pyrimidin-1-yl)ethyl)-1H-isochromen-1-one single enantiomer (intermediate T.3, second eluted enantiomer under the conditions described above, 0.365 g, 0.557 mmol) was dissolved in a solution of 1M HCl in EtOH (1.78 mL) and the mixture was stirred at RT overnight. The volatiles were removed under reduced pressure and the residue was purified by flash chromatography on silica gel cartridge (DCM to DCM:MeOH=95:5) to afford title compound as a yellow solid (0.260 g, 0.481 mmol, 86%). This compound proved to be the first eluted enantiomer under Chiral HPLC conditions of Method A11: Rt=13.6 min, ee=99.6%.
