실험 절차

A solution of 2-amino-9-(2-hydroxyethoxymethyl)adenine (0.5 g) in 97% formic acid (2.5 ml) was stirred in an ice bath for 3 hours, and then at room temperature overnight. Dry ether (80 ml) was added and the mixture chilled. The solid was removed by filtration and dissolved in hot acetonitrile (125 ml); residual solids were removed by filtration. The filtrate was applied to a column containing silica gel (14 g) in acetonitrile. The column was eluted with dry acetone. The eluate was evaporated and the residual solid recrystallized from acetonitrile to give 2-amino-9-(2-formyloxyethoxymethyl)adenine (93 mg, m.p. 238°-240° C.).
