Procedure

0.5 g of L-phenylalanyl-N-(2-benzoyl-4-chlorophenyl)-N-methyl-L-alaninamide was dissolved in a minimum amount of methanol at room temperature and treated, by titration, with an exact equivalent of 1-N hydrochloric acid. The solvent was removed from the resulting solution by evaporation in vacuo at room temperature and finally by lyophilisation to give, in quantitative yield, L-phenylalanyl-N-(2-benzoyl-4-chlorophenyl)-N-methyl-L-alaninamide hydrochloride as a white hygroscopic light-sensitive amorphous powder of melting point 130°-140° C. (slow decomposition): [α]D20 =-40.0° (c=1 in water).
