Cesium carbonate → 2-(4-Carboxymethyl-phenylsulfanylmethyl)-benzoic acid 2,2,2-trichloro-ethyl ester

Participants

Reaction Steps

The titled compound was prepared according to the method described for 2-(3-carboxymethyl-phenylsulfanylmethyl)-benzoic acid 2,2,2-trichloro-ethyl ester above from 4-mercapto-phenylacetic acid (0.73 g, 4.33 mmol), 2-bromomethyl-benzoic acid 2,2,2-trichloro-ethyl ester (1.50 g, 4.33 mmol), cesium carbonate (1.69 g, 5.20 mmol) and DMF (25 mL). The crude material (1.88 g, 100%) was used for the next step without further purification; Mass spectrum: M−H+ 432.
