실험 절차

5-(R)-(4-bromobenzyl)-3-(5-acetamino-3-chlorophenyl)-5-methylimidazoline-2,4-dione (prepared by the process described in Example 1 from the isocyanate derivative of (R)-α-methyl-4-bromophenylalanine methyl ester and 5-acetamino-3-chloroaniline) was hydrolyzed by heating in 2N HCl to give 5-(R)-(4-bromobenzyl)-3-(5-amino-3-chlorophenyl)-5-methylimidazoline-2,4-dione. Sandmeyer reaction with NaNO2, CuCN and KCN provided the title compound as a resin.
