N,4,6-trimethoxy-1,3,5-triazin-2-amine → N-[(4,6-dimethoxy-1,3,5-triazin-2-yl)(methoxy)aminocarbonyl]-2-(methylsulfonyl)benzenesulfonamide

Participants

Reaction Steps

To a stirred suspension of N,4,6-trimethoxy-1,3,5-triazin-2-amine (0.01 mol) in dry methylene chloride (24 ml) is added 2-methylsulfonylbenzenesulfonyl isocyanate (0.014 mol). The mixture is stirred at ambient temperature for 24 hours. The solvent is then evaporated under reduced pressure. The residue is stirred in 1-chlorobutane (50 ml) for 5 hours. The solid is then filtered, washed with ether and dried to yield N-[(4,6-dimethoxy-1,3,5-triazin-2-yl)(methoxy)aminocarbonyl]-2-(methylsulfonyl)benzenesulfonamide.
