Process for preparing 2,6-substituted-9-(1,3-dihydroxy-2-propoxymethyl)-purines and certain derivatives

摘要

Process and novel intermediates for preparing 9-(1,3-dihydroxy-2-propoxymethyl)guanine and 2,6-diamino-9-(1,3-dihydroxy-2-propoxymethyl)purine and certain esters thereof. The present process and intermediates reduce the number of reaction steps to prepare these compounds as compared to prior processes. The products are useful as antiviral agents.
