2-Bromo-1-[1-(4-Chlorophenyl)cyclobutyl]ethanone → 1-[1-(4-Chlorophenyl)cyclobutyl]-2-(3,4,5,6-tetrahydropyrimidin-2-ylthio)ethanone hydrobromide

Participants

Reaction Steps

A solution of 2-bromo-1-[1-(4-chlorophenyl)cyclobutyl]ethanone (2.9 g) in acetone (25 ml) was added to a solution of 3,4,5,6-tetrahydropyrimidine-2-thiol (1.2 g) in acetone (150 ml), then the mixture was heated under reflux for 1 hour, and allowed to cool to ambient temperature. The resulting solid was collected by filtration and dried in vacuo at ambient temperature to give 1-[1-(4-chlorophenyl)cyclobutyl]-2-(3,4,5,6-tetrahydropyrimidin-2-ylthio)ethanone hydrobromide as a white solid (3.5 g), m.p. 205° C.
