Reaction Steps

1.1 g of methyl 3-methylsulfonyl-4-trifluoromethylbenzoate [m.p. 146°-147°; obtainable by reaction of methyl 3-methylsulfonyl-4-bromobenzoate with potassium trifluoroacetate in the presence of CuI and tetramethylammonium iodide in toluene] are added to a solution of 928 mg of guanidine in 15 ml of methanol. The mixture is stirred for 45 minutes at 50° and, after removal of the solvent and customary working up, N-diaminomethylene3-methylsulfonyl-4-trifluoromethylbenzamide, m.p. 233°-234°, is obtained.
