Step-1: Synthesis of tert-butyl 6-(2-allyl-1-(6-(2-hydroxypropan-2-yl)pyridin-2-yl)-3-oxo-2,3-dihydro-1H-pyrazolo[3,4-d]pyrimidin-6-ylamino)-3,4-dihydroisoquinoline-2(1H)-carboxylate To a stirred solution of 2-allyl-1-(6-(2-hydroxypropan-2-yl)pyridin-2-yl)-6-(methylthio)-1H-pyrazolo[3,4-d]pyrimidin-3(2H)-one (300 mg, 0.84 mmol, 1.0 eq) in toluene (5 mL) was added m-CPBA (361 mg, 2.10 mmol, 2.5 eq) and allowed to stir at RT for 30 min. tert-Butyl 6-amino-3,4-dihydroisoquinoline-2(1H)-carboxylate (208 mg, 0.84 mmol, 1.0 eq) and DIPEA (433 mg, 3.36 mmol, 4.0 eq) were added and allowed to stir at RT for 12 h. Progress of reaction was monitored by LCMS. After completion of reaction, precipitated compound was filtered off, washed with toluene (3 mL) and dried under reduced pressure to obtain tert-butyl 6-(2-allyl-1-(6-(2-hydroxypropan-2-yl)pyridin-2-yl)-3-oxo-2,3-dihydro-1H-pyrazolo[3,4-d]pyrimidin-6-ylamino)-3,4-dihydroisoquinoline-2(1H)-carboxylate (220 mg, 47.00%).

164148-92-9, 164148-92-9 tert-Butyl 6-amino-3,4-dihydroisoquinoline-2(1H)-carboxylate 2756371, aisoquinoline compound, is more and more widely used in various fields.
