摘要：A new process has been developed for the synthesis of optionally substituted1,2,3,5-tetrahydroimidazo 2,1-b!quinazolin-2-ones. In particular, the process is particularlyadaptable for the preparation of the 5,6-disubstituted compounds, e.g., 5,6-dimethyl-1,2,3,5- tetrahydroimidazo- 2,1-b!quinazolin-2-one. The compounds so prepared areuseful as blood platelet anti-aggregative and/or antihypertensive agents in mammals,including humans.
