Procedure
To a mixture of thioanisole (5.0 g) and propionyl chloride (3.9 ml) at 0° C. in dichloroethane (80 ml) was added AlCl3 (6.4 g) in portions. The mixture was stirred 12 hours at ambient temperature, poured into water (200 ml) and conc. HCl (2 ml), then extracted with CH2Cl2. The extract was reduced to dryness to provide the title compound mp 60°-61° C. after purification by chromatography on silica gel.
