Reaction Steps

2 mL of 4.0 N HCl in 1,4-dioxane was added to a solution of tert-butyl 4-{2-[7-[2-amino-6-(4-methylpiperazin-1-yl)pyrimidin-4-yl]-3,4-dihydroisoquinolin-2(1H)-yl]-2-oxoethyl}piperidine-1-carboxylate (25 mg, 0.045 mmol) in methanol (1.0 mL). The reaction mixture was stirred at r.t. for 2 h. The volatiles were removed under reduced pressure to afford the product as an HCl salt (25 mg, 98%). Analytic LCMS (M+H)+: m/z=450.2.
