Participants

Reaction Steps

A stirred solution of 2-methoxyphenyl benzoate (10 g) in dichloromethane (100 mL) from 0°-5° C. is treated dropwise with chlorosulfonic acid (2.9 mL) and the solution is then stirred for 3 hours from 0°-5° C. The precipitate which forms is filtered off, washed with cold dichloromethane, and dried in vacuo, to give 3-benzoyloxy-4-methoxybenzenesulfonic acid (11.45 g), in the form of a white solid, m.p. 139°-140° C.
