Reaction Steps

To a flask of 2-(1-((2-(2-(dibenzylamino)-1H-benzo[d]imidazol-1-yl)-9-methyl-6-morpholino-9H-purin-8-yl)methyl)piperidin-4-yl)propan-2-ol (125 mg) in Ethanol (5.4 mL) was added 10% Palladium on Carbon (0.2 g) and Acetic acid (83 uL). The flask was purged with a nitrogen balloon and then placed under a Hydrogen balloon. The reaction was heated at 70° C. for 48 hours. The reaction was filtered thru celite and the celite cake was rinsed with a mixture of 1% acetic acid in methanol several times. The solvent was concentrated to dryness to give 70 mg of crude 2-(1-((2-(2-amino-1H-benzo[d]imidazol-1-yl)-9-methyl-6-morpholino-9H-purin-8-yl)methyl)piperidin-4-yl)propan-2-ol, 70 mg of which was added to HATU (105 mg), DIPEA (0.12 mL) and acetic acid (24 uL) in DMF (0.8 mL). Upon completion, the reaction was diluted with Ethyl acetate and extracted with water. The organic layer was dried, filtered and concentrated to give crude product. The crude was purified via reverse phase HPLC to afford 11.5 mg of 517 as a white solid. MS (Q1) 548.3 (M)+
