Procedure

4.0 g (0.026 mol) of 2-mercaptonicotinic acid, 5.7 g (0.026 mol) of 4,6-dimethoxyl-2-methylsulfonylpyrimidine and 7.2 g (0.052 mol) of potassium carbonate were weighed, and 70 ml of dimethylformamide was added thereto and the mixture was stirred at 80° C. for 2 hours. The resultant mixture was poured into water, and was washed with 100 ml of ethyl acetate. The aqueous layer was then acidified with 10% HCl aqueous solution to precipitate a crystal. The crystal thus precipitated was filtrated out, and was washed with water and was dried. The crystal was then recrystallized with methanol to obtain 5.3 g of a light-yellowish crystal of the aimed product.
