Reaction Steps

To a stirred solution of ((S)—N-(1-(1,8-dichloroisoquinolin-3-yl)ethyl)-9-(4-methoxybenzyl)-9H-purin-6-amine 1 (1.5 g, 3.1 mmol, 1.0 eq) and tetrakis(triphenylphosphine)palladium (181 mg, 0.16 mmol, 0.05 eq) in DMF (50 mL) at RT, dicyanozine (476 mg, 4.06 mmol, 1.3 eq) was added and the resulting mixture was stirred at 100° C. overnight. The reaction mixture was poured into water (100 mL) and extracted with DCM (3×100 mL). The combined organic layers were washed with brine, dried over Na2SO4 and filtered. The filtrate was concentrated in vacuo and the residue was purified by flash column chromatography on silica gel (1-10% MeOH-DCM) to afford the product (S)-8-chloro-3-(1-((9-(4-methoxybenzyl)-9H-purin-6-yl)amino)ethyl)isoquinoline-1-carbonitrile 29.
