Procedure

A mixture of cyclohexanecarboxylic acid [2-(2-amino-5-benzoyl-benzylamino)-ethyl]-amide (0.0032 mol) in ethanol (30 mL) was stirred at room temperature. Cyanogen bromine (0.0048 mol) was added. The reaction mixture was stirred and refluxed for 2 hours, then cooled and stirred overnight at room temperature resulting in a precipitate. The precipitate was filtered off, washed with diisopropyl ether and dried to yield the title compound as a residue.
