HCID 54048955HCID 54048955, compound

Procedure

The title compound is prepared by reductive alkylation of 2-n-butyl-3-(2-chlorophenyl)methylhistidine ethyl ester with benzaldehyde in the presence of sodium cyanoborohydride to give 3-[(2-chlorophenyl)methyl]-2-n-butyl-N-benzylhistidine ethyl ester. Hydrolysis of the ester group is accomplished according to Example 2 (iii) to provide the title compound.
