Procedure

To a suspension of 2-amino-4-chloro-N-(1,1-dimethylethyl)-5-pyrimidinesulfonamide (2.64 g, 10 mmol) in 7 mL dimethylether was added meta-toluidine (2.46 g, 23 mmol) and the reaction stirred at room temperature for 1 hour and then at 60° C. for 1/2 hour. The solvent was removed and the residue taken up in ethyl acetate. The ethyl acetate was washed with water, saline, dried, and the solvent removed in vacuo. The residue was triturated with ether and the crystals collected by suction filtration and dried to give 2.10 g of the identical product obtained in Step 1.
