Reaction Steps

tert-Butyl 4-{2-[2-amino-6-(4-methylpiperazin-1-yl)pyrimidin-4-yl]-3-methyl-1,2,3,4-tetrahydroisoquinolin-7-yl}piperidine-1-carboxylate (0.20 g, 0.38 mmol) in ethyl acetate (1.0 mL) was treated with 4.0 M of Hydrogen chloride in 1,4-dioxane (1.0 mL, 4.0 mmol) at r.t. for 2 h. The mixture was diluted with ethyl ether, and centrifugalized. The solvents were decanted. The residue was dried in-vacuo to afford the desired product as HCl salt which was directly used in next step reaction without further purification. LCMS (M+H)+: m/z=422.2.
