Procedure

A solution of 1,3-bis{[p-(1,1,2,2-tetrafluoroethoxy)benzylidene]amino}guanidine (29.84 g, 0.06 mol), diisopropylethylamine, (15.51 g, 0.12 mol) and dimethylcarbamoyl chloride (129.2 g, 0.12 mol) in acetonitrile (200 mL) is stirred at reflux for 22 hours. The reaction mixture is cooled, and the acetonitrile is evaporated under reduced pressure. The residue is dissolved in ethyl acetate (250 mL), and the organic solution is washed with water, saturated NaCl and dried over Na2SO4. The solvent is evaporated under reduced pressure, and the residue is crystallized from benzene-hexanes to give the desired product as a yellow solid, mp 141.5°-143.5° C. in 92.9% yield.
