Triethylamine → 1-(tert-butoxycarbonyl)piperidin-4-yl 7-[2-amino-6-(4-methylpiperazin-1-yl)pyrimidin-4-yl]-3,4-dihydroisoquinoline-2(1H)-carboxylate

Participants

Reaction Steps

tert-Butyl 4-{[(4-nitrophenoxy)carbonyl]oxy}piperidine-1-carboxylate (0.093 g, 0.25 mmol) was added to a solution of 4-(4-methylpiperazin-1-yl)-6-(1,2,3,4-tetrahydroisoquinolin-7-yl)pyrimidin-2-amine HCl salt (0.10 g, 0.23 mmol) and triethylamine (0.13 mL, 0.92 mmol) in acetonitrile (5.0 mL). The reaction mixture was stirred at r.t. overnight. The mixture was diluted with water, and extracted with ethyl acetate (3×10 mL). The combined organic layers were dried over MgSO4, filtered and concentrated under reduced pressure. The residue was purified by flash chromatography on a silica gel column with MeOH in dichloromethane (0-10%) to afford the desired product (0.10 g, 79%). Analytic LCMS (M+H)+: m/z=552.3.
