Procedure

A mixture of (R)-3-(5-acetoxyhexyl)-7,8-dihydro-1-methyl-1H-imidazo[2,1-f]-purine-2,4(3H,6H)-dione (700 mg, 2.0 mmol) and a 1.0 M solution of hydrogen chloride in diethyl ether (5 ml, 5.0 mmol) in methanol (100 ml) was stirred at room temperature overnight. After concentrating under reduced pressure, the residual solid was treated with ethyl acetate (20 ml) and stirred at room temperature for 2 hours. Filtration provided (R)-7,8-dihydro-3-(5-hydroxyhexyl)-1-methyl-1H-imidazo[2,1-f]-purine-2,4(3H,6H)-dione (CT-13430) (400 mg, 65% yield) as a white powder.
