To 1.5 ml (2N) trimethylaluminum in 5 ml dry toluene under N2 was added dropwise 0.48 g (6.0 mmole) 2-propanethiol in 2 ml toluene. The resultant aluminum reagent was stirred at room temperature for 15 minutes, and 0.95 g (2.5 mmole) N-[(4-methoxy-6-methyl-1,3,5-triazin-2-yl)aminocarbonyl]-2-methoxycarbonylbenzenesulfonamide was added in one portion. The suspension was heated to 80° C. for 3 hours, cooled to room temperature and 10% HCl (15 ml) was added. The mixture was stirred until a fine solid precipitated which was filtered off, washed with hexanes and air dried to yield 0.4 g of product melting at 155°-158° C. It showed infrared absorption peaks consistent for N-[(4-methoxy-6-methyl-1,3,5-triazin-2-yl)aminocarbonyl]-2-isopropylthiocarbonylbenzenesulfonamide.
