Reaction Steps

5.0 g of methyl 3-bromomethyl-2-chloro-4-methanesulfonylbenzoate was added to a solution of 0.4 g of 18-crown-6 and 1.9 g of potassium cyanide in 50 ml of acetonitrile. The mixture was stirred for 72 hours at room temperature. After filtering off the solid, water was added to the filtrate, and the mixture was extracted with chloroform. After washing the extract with water and drying it, the solvent was distilled off to obtain a crude product. The crude product was purified by short silica gel column chlomatography (eluent: chloroform) to obtain 4.1 g of the desired product. Melting point: 151°-155° C.
