Procedure

To a mixture of (R)-3-(4-phenoxyphenyl)-1-(piperidin-3-yl)-1H-pyrazolo[3,4-d]pyrimidin-4-amine (6) (38.62 g), glycolic acid (9.13 g) and triethylamine (27.90 mL) in THF (500 mL) stirring in an ice bath, was added HATU (45.63 g) in one portion. The reaction was allowed to warm up to room temperature and stirred overnight (16 hrs). Solvent was removed by rotoevaporation. The residue was diluted with dichloromethane (500 mL), washed with aqueous NaOH solution (10%, 300 mL). The solid was filtered off and the bi-layer system was separated. The organic layer was washed with brine, dried (Na2SO4), filtered and evaporated in vacuo. The residue was triturated with acetonitrile (300 mL) with some heating and cooled to room temperature. The mixture was filtered after sitting at room temperature overnight (16 hrs) and filtered. The solid collected was washed with small amount of acetonitrile and dried under high vacuo to provide the title compound a white powder with slight pink color (34.8 g).
