Reaction Conditions

Reaction Steps

A mixture of 158 g (0.87 mole) of 4-methylthiophenylacetic acid and 150 ml (2 moles) of thionyl chloride was heated at 90° C. for 2 hours. After completion of the reaction, an excess of thionyl chloride was distilled off under reduced pressure, giving about 120 g of 4-methylthiophenylacetyl chloride as a black oily product. The oily product thus obtained was subjected to the subsequent reaction without isolation and purification.
