Procedure

To a mixture of (S)—N-(1-(1,8-dichloroisoquinolin-3-yl)ethyl)-9H-purin-6-amine 38 (300 mg, 0.84 mmol, 1 eq) in 1,4-dioxane (10 mL) at RT, 1-methylpiperazine (167 mg, 1.68 mmol, 2 eq) was added and the resulting mixture was stirred at reflux for 8 h. The mixture was allowed to cool to RT, concentrated in vacuo and the residue was purified by flash column chromatography on silica gel (1-5% MeOH-DCM) to afford the product, (S)—N-(1-(8-chloro-1-(4-methylpiperazin-1-yl)isoquinolin-3-yl)ethyl)-9H-purin-6-amine 46. ESI-MS m/z: 423.2 [M+H]+.
