Procedure

To a suspension of methyl 1-[[(4,6-dimethoxypyrimidin-2-yl)aminothiocarbonyl]aminosulfonyl]-2-naphthalenecarboxylate in 200 ml of anhydrous tetrahydrofuran can be added 16.7 ml of 3M NaOCH3 /MeOH solution. The resulting reaction mixture can be heated to reflux, 3.1 ml of methyl iodide in 10 ml of anhydrous tetrahydrofuran can be added; and the reaction mixture can be refluxed for 3 hours. The reaction mixture can be cooled to cause the formation of a precipitate which can be filtered off and washed with tetrahydrofuran to afford the desired product.
