Procedure

Add sodium hydride (1.21 g, 95%) to a solution of 4-cyanophenol (5.71 g, 47.98 mmol) in anhydrous TI-IF (70 mL) and stir the mixture for 5 min. Add dimethylthiocarbamoyl chloride (5.93 g, 47.98 mmol) and heat the mixture at reflux for 3 h. Cool the mixture to room temperature and add water. Extract the aqueous phase with EtOAc, dry the organic phase over MgSO4, filter and concentrate in vacuo to obtain a solid. Wash the solid with diethyl ether, filter and dry in vacuo to obtain the desired intermediate as a solid (4.41 g, 75%).
