Reaction Steps
A benzene solution (25 ml.) containing 6,7-dichloro-2,3-dihydro-5-(2-thenoyl)benzofuran-2-carboxylic acid (3.4 g., 0.01 mole) and thionyl chloride (2 ml.) is refluxed for two hours. Evaporation of the benzene and excess thionyl chloride leaves the 6,7-dichloro-2,3-dihydro-5-(2-thenoyl)benzofuran-2-carbonyl chloride which is used in Step B without further purification.
