Reaction Steps

A mixture of 5-(3-cyclopropyl-1,3-dioxoprop-1-yl)-3,4-dimethoxybenzo[b]thiophene (0.5 g) and triethyl orthoformate (0.73 g) was heated under reflux with acetic anhydride (10 ml) for 3 hours. After cooling and addition of toluene the solution was evaporated to dryness to yield 5-(3-cyclopropyl-2-ethoxymethylene-1,3-dioxoprop-1-yl)-3,4-dimethoxybenzo[b]thiophene as a red oil.
