実験手順

A suspension of tert-butyl 3-((9-methyl-2-(2-ethyl-1H-benzo[d]imidazol-1-yl)-6-morpholino-9H-purin-8-yl)methylene)azetidine-1-carboxylate (1.1 g, 2.1 mmol) and Pd/C (10 wt %, 0.4 g) in ethanol (25 mL) was stirred under a hydrogen atmosphere (balloon) at room temperature for 24 hours. The reaction mixture was then filtered through celite and concentrated. The crude product was purified by flash chromatography (0-5% MeOH in DCM) to give the title compound (0.64 g, 58%). LCMS m/z: 547.2 (MH+)
