Reaction Steps

6-Amino-2-(2-methoxy-ethoxy)-9-(3-pyrrolidin-1-ylmethyl-benzyl)-9H-purin-8-ol (Example A) (60 mg, 0.15 mmol) was dissolved in dichloromethane (2 mL). N,N-diisopropylethylamine (0.1 mL) was added and the mixture was cooled to 0° C. Ethylchloroformate (0.04 mL, 0.42 mmol) was added. After stirring for 30 minutes, the reaction was quenched with water and concentrated under vacuum. Purification by preparative reverse phase HPLC (5-45% acetonitrile/40 mM aqueous HCl) gave 9-(3-(pyrrolidin-1-ylmethyl)benzyl)-6-amino-2-(2-methoxyethoxy)-9H-purin-8-yl ethyl carbonate (Example Q) (24 mg) as a white glassy solid, HCl salt.
