Abstract

The reaction of 4-dialkylamino-6-chloro-2-methylthiopyrimidine-5-carbaldehydes with ethyl mercaptoacetate in the presence of triethylamine gives the corresponding ethyl esters of thieno[2,3-d]-pyrimidine-6-carboxylic acids. These esters were subjected to alkaline hydrolysis, hydrazinolysis, and lithium aluminum hydride reduction to give the corresponding acids, hydrazides, and (thieno[2,3-d]-pyrimidin-6-yl)methanols.
