*Reaction file type CDX
*Procedure To a stirred solution of 4-iodophenol (7.70 g, 35.0 mmol) in DMF (35 mL), in a 100 mL rbf, was added NaH (1.40 g of a 60% dispersion in mineral oil, 35.0 mmol, 1.00 eq.) in small portions, at r.t. After 10 minutes the reaction vessel was heated to 80 ºC over a period of 45 minutes, and then allowed to cool to r.t. before adding dimethylthiocarbamoyl chloride (5.20 g, 42.1 mmol, 1.20 eq.) in small portions. The reaction mixture was stirred for 20 h at r.t., monitoring the disappearance of starting materials by TLC. Once most of the DMF had been removed with a rotary evaporator, the mixture was poured into DCM and washed with water; the water was extracted with DCM, and the combined organic phases were dried over anhydrous MgSO4; evaporation of the solvent afforded the crude title compound (11.42 g). The pure product, a white solid (6.93 g, 22.6 mmol, yield 64%), was obtained by column chromatography on silica gel, using as eluent (8/1) hexane/DCM (Rf 0.5).
*Yield (%) 64 %
*Type of Yield Isolated pure product
