When serendipity knocks on the door: Synthesis and Physicochemical Characterization of 7-Chloro-2,3-dihydro-5H-thiazolo[3,2-a]pyrimidin-5-one
(Sociedade Brasileira de Quimica, 2019-03-19)
Herein, we present the serendipitous obtaining of 7-chloro-2,3-dihydro-5H-thiazolo [3,2-a]pyrimidin-5-one in 40% yield by using POCl3 and a thiobarbituric acid derivative. The thiazolopyrimidine derivative was characterized ...
