Procedure

A mixture of 4-cyanophenacyl bromide (3.0 g), methyl thiosalicylate (2.25 g), sodium methoxide (1.52 g) and ethanol (100 ml) was boiled under reflux for 3.5 hours. The mixture was cooled and diluted with 2M hydrochloric acid (100 ml). A precipitate was collected by filtration and recrystallized from ethanol to give 2-(4-cyanobenzoyl)-3-hydroxybenzo[b]thiophene.
