  • Patent number: 6040446
    Abstract: Process and novel intermediates for preparing the L-mono-valine ester of 2-(2-amino-1,6-dihydro-6-oxo-purin-9-yl)methoxy-1,3-propanediol and its pharmaceutically acceptable salts. The present process and intermediates provide for reduced impurities in the mono-valine ester end-product and lower overall production costs. The process involves the condensation of a silylated guanine compound with a substituted glycerol derivative and esterification of this product with an L-valine derivative. These mono-valine products are of value as antiviral agents with improved absorption.
