Reaction Steps

The HCl salt of 3-(2-(2-isopropyl-1H-benzo[d]imidazol-1-yl)-9-methyl-6-morpholino-9H-purin-8-yl)piperidin-3-ol (80 mg) was reacted with isopropyl iodide (1.5 eq) and potassium carbonate (5 eq) in a 1:1 mixture of DMF and Acetonitrile (2 mL). The reaction was heated at 75° C. for 18 hours until complete. The reaction mixture was diluted with Ethyl acetate and extracted with a saturated ammonium chloride solution. The organic layer was dried, filtered and concentrated to give 581 [4.6 mg; MS (Q1) 491.3 (M)+] and 582 [4.7 mg; MS (Q1) 491.3 (M)+] following reverse phase purification and subsequent chiral separation.
