A solution of 0.2 g (1.0 mmol) of 2,6-dimethoxy-5-nitro-4-pyrimidinamine and 0.6 g (2.4 mmol) of 2-carbomethoxybenzenesulfonyl isocyanate in 15 ml of methylene chloride was stirred at ambient temperature and pressure for 12 hours under anhydrous conditions. The solvent was then evaporated under reduced pressure. The residue was stirred in n-butyl chloride (70 ml). The solid was then collected by filtration, washed with ether and then dried in an oven to afford 0.4 g of the title compound, m.p. 150°-152° dec.
