Reaction Steps

6-Amino-2-(2-methoxy-ethoxy)-9-(3-pyrrolidin-1-ylmethyl-benzyl)-9H-purin-8-ol (Example A) (31 mg, 0.078 mmol) was dissolved in DMF (2 mL). Anhydrous potassium carbonate (50 mg) was added followed by p-methoxybenzyl chloride (13.7 μL, 0.101 mmol). The mixture was stirred at ambient temperature overnight. The reaction mixture was diluted with dichloromethane, washed with water and brine, dried with Na2SO4 and evaporated under vacuum. Purification by preparative HPLC (5-60% acetonitrile/40 mM aqueous HCl) gave 6-amino-7-(4-methoxy-benzyl)-2-(2-methoxy-ethoxy)-9-(3-pyrrolidin-1-ylmethyl-benzyl)-7,9-dihydro-purin-8-one (Example P) (6 mg) as the HCl salt.
