Reaction Steps

To a solution of 3-[2-(2-ethylbenzoimidazol-1-yl)-9-methyl-6-morpholin-4-yl-9H-purin-8-yl]-3-hydroxypiperidine-1-carboxylic acid tert-butyl ester (1.0 g, 1.78 mmol) in DCM (5 mL) and MeOH (1 mL) was added 4M HCl in dioxane (5 mL). The resulting mixture was allowed to stir for 2 h at r.t. before Et2O was added. The resulting precipitate was collected by filtration, washed with Et2O and dried in vacuo affording 3-[2-(2-Ethylbenzoimidazol-1-yl)-9-methyl-6-morpholin-4-yl-9H-purin-8-yl]piperidin-3-ol dihydrochloride (870 mg, 92%). LCMS (method H): RT 1.84 min [M+H]+ 463.3
