This invention relates to a new class of compounds of the indole series. Particularly, it relates to novel thio esters of 1-(p-chlorobenzoyl)-5-methoxy-2-methylindole-3-acetic acid. These novel compounds are prepared by reacting 1-(p-chlorobenzoyl)-5-methoxy-2-methylindole-3-acetic acid with an appropriate thiol and diethyl phosphorocyanidate or diphenyl phosphorazidate in the presence of triethylamine in a dimethylformamide solution. These compounds are useful anti-inflammatory agents.

A method to synthesize thioethers and thioesters directly from readily available sulfonyl chlorides is reported. We demonstrate that a transient intermediate formed during phosphine-mediated deoxygenation of sulfonyl chlorides can be trapped in situ by activated alcohols or carboxylic acids to effect carbon–sulfurbond formation. The method is operationally simple and tolerates a broad range of functional
