Reaction Steps

A mixture of 6.0 g of 4-mercapto-toluene and 9.2 g of potassium t-butoxide is stirred at room temperature under a nitrogen atmosphere in 50 ml of dimethylsulfoxide for 10 minutes followed by the addition of 11.5 g of 4-bromobenzoic acid and 0.2 g of copper metal. The reaction mixture is stirred at 210° C. for 16 hours. The reaction mixture is poured over crushed ice and filtered through diatomaceous earth. The filtrate is acidified with HCl until pH 2. The resulting solid is collected, washed with water and 60 ml of petroleum ether to give 8.5 g of the desired product, m.p. 105°-107° C., M+H=245.
