Procedure
4-[3-(3-Cyanophenyl)-ureido]-benzenesulfonyl chloride (1.0 g, 2.98 mmol) was dissolved in 20 ml THF, 2,3,6-trifluoro-benzylamine (0.48 g, 2.98 mmol) and DIEA (0.52 ml, 2.98 mmol) were added and the solution was refluxed for about 3 h. The solvent was removed in vacuo and the residue cristallized with ethanol/water. The solid was filtered and dried in vacuo. Yield 94% of 4-[3-(3-cyano-phenyl)-ureido]-N-(2,3,6-trifluorobenzyl)-benzenesulfonamide.
