実験手順
A mixture of 2-(2-amino-5-benzoyl-benzylamino)-ethanesulfonic acid cyclohexyl-methyl-amide (0.0054 mol) and cyanogen bromide (0.0080 mol) in ethanol (100 mL) was stirred and refluxed for 2 hours, and then the reaction mixture was cooled to room temperature. After filtration, the filter residue was washed with diisopropyl ether and dried under vacuum to yield the title compound as a solid.
