Procedure

DIPEA (0.253 ml, 1.452 mmol) was added at 0° C. to a stirred suspension of 3-(1-(4-amino-3-iodo-1H-pyrazolo[3,4-d]pyrimidin-1-yl)ethyl)-4-(1,2,3,6-tetrahydropyridin-4-yl)-1H-isochromen-1-one hydrochloride (Intermediate D23, 0.200 g, 0.363 mmol), HATU (0.166 g, 0.436 mmol) and 4-dimethylaminobutyric acid hydrochloride (0.073 g, 0.436 mmol) in THF/DMF 5:1 (6 mL). The mixture was stirred at 0° C. for 15 min, then at rt for further 45 min. The reaction mixture was poured into saturated aqueous sodium bicarbonate and extracted with DCM. The collected organic phases were concentrated under reduced pressure and the crude purified by RP-flash chromatography (Biotage 30 g C18 column, gradient elution from 100:0 to 70:30 A/B in 15 CV; A: water/MeCN 95/5+0.01% HCOOH, B: water/MeCN 5/95+0.01% HCOOH) to give title compound (0.153 g, 0.227 mmol, 62.6% yield) as a white powder.
