Procedure
To a solution of 1.38 g of p-chlorophenol and 0.585 g of sodium methoxide in 10 ml of methanol is added a solution of 3.53 g of methyl α-bromo-α-[p-(p-methylsulfonylphenoxy)phenyl]acetate in 15 ml of methanol. The mixture is refluxed for 20 hours, chilled and filtered to give 2.71 g of white crystals, mp 182°-183° C. Recrystallization by heating in 75 ml of acetone and adding 20 ml of dichloromethane, followed by adding hexane gives on chilling the product as white crystals, mp 182°-183° C.
