Versuchsvorschrift

A mixture of 3-(2-bromoacetyl)benzo[b]thiophen (10.0 g), 2-imidazolidinethione (4.0 g), ethanol (120 ml) and acetic acid (80 ml) was heated under reflux for 24 hours then allowed to cool to ambient temperature. The resulting solid was collected by filtration and dried in vacuo at ambient temperature to give 3-(benzo[b]thiophen-3-yl)-5,6-dihydroimidazo[2,1-b]thiazole monohydrobromide 1.8 hydrate as a white solid (11.6 g), m.p. 227°-229° C.
