Abstract

PURPOSE: To obtain the titled substance useful as a telangiectatic agent, etc. simply, economically, and in high yield, by reacting 3,7-dimethyluric acid as a raw material with a compound, e.g., 1-bromohexanone-5, etc., followed by removing carbonyl group.
CONSTITUTION: 3,7-Dimethyluric acid shown by the formula I is reacted with a compound shown by the formula II (X is halogen, hydroxyl group, alkyl or arylsulfonyloxy) in a solvent, e.g., methanol, etc., to give a reaction product, which is reacted with formic acid so that a carbonyl group is removed, to give a compound shown by the formula III. The compound shown by the formula I, for example, is obtained easily by reacting 1-methyl-5-methylamino-6-aminouracil prepared from 6- aminouracil with a carbonylating agent, e.g., chlorocarbonic acid ester, etc.
