Abstract
9-D-Erythrityladenine was synthesized from 4, 6-dichloro-5-aminopyrimidine and 2, 4-O-ethylidene-erythritylamine, followed by the cyclization with acetic anhydride and ethyl orthoformate. The phosphorylation of erythrityladenine was achieved by the general method using P-diphenyl P'-morpholino pyrophosphorochloridate described in earlier report. 2', 3'-Di-O-acetylerythrityladenine 4'-triphosphate was obtained as decahydrate in a pure state.
