Procedure

A mixture of ethyl 4-(4-pyridylthio)benzoate (400 mg, 1.54 mmol) and 5 N aqueous sodium hydroxide (2 mL) in 1:1 tetrahydrofuran/methanol (2 mL) was stirred at room temperature for 18 h. The mixture was diluted with water and washed with diethyl ether. The aqueous layer was acidified to pH 6 with concentrated hydrochloric acid. The resulting precipitate was collected via vacuum filtration to provide 280 mg (78%) of the title compound as a pale yellow solid.

Workup

  1. washwashed with diethyl ether
