Participants

Reaction Steps

A mixture of 6-acetyl benzo[b]thiophene (10.57 g, 60 mmole), p-toluenesulfonic acid (1.65 g) and ethylene glycol (33 ml) was heated to reflux in toluene (250 ml) for 2 hours with the continuous removal of H2O using a Dean-Stark trap. The reaction mixture was allowed to cool to room temperature. Then extracted with 20% saturated NaHCO3 (150 ml) and H2O (2×150 ml). After drying over Na2SO4, the solvent was evaporated in vacuo and the residue was crystallized from hexanes (50 ml) yielding 9.66 g (73%) of product.
