Hydrochloric Acid → 4-(9-methyl-2-(2-methyl-1H-benzo[d]imidazol-1-yl)-8-(piperidin-4-ylmethyl)-9H-purin-6-yl)morpholine

Participants

Reaction Steps

To a solution of tert-butyl 4-((9-methyl-2-(2-methyl-1H-benzo[d]imidazol-1-yl)-6-morpholino-9H-purin-8-yl)methyl)piperidine-1-carboxylate (0.36 g, 0.66 mmol) in 1,4-dioxane (10 mL) was added a 4M solution of hydrogen chloride in 1,4-dioxane. The reaction mixture was then stirred at room temperature for 1 hour. The resulting suspension was then filtered. The collected solid was washed 1,4-dioxane and dried under vacuum to give 520 (hydrochloride salt) as an off-white solid (0.34 g, quant.). LCMS m/z: 484.2 (MH+)
