Procedure

Trimethylaluminum (6.0 ml, 2 M) is charged via syringe to 15 ml dry toluene under nitrogen atmosphere and 3.8 g N-[(5-chloro-4,6-dimethylpyrimidin-2-yl)-aminocarbonyl]-2-methoxycarbonylbenzenesulfonamide is added portionwise. After stirring at room temperature for one hour, methyl mercaptan (gas) is passed through the reaction mixture until the initial temperature rise subsided, whereupon the addition is discontinued. The reaction mixture is allowed to stir at room temperature for 1 hour, and quenched with 25 ml of 10% HCl. The resultant white suspension is filtered to give the desired product.
