Procedure

92 mg (0.160 mmol) of diastereomer B of (2R*,4S*)-2-benzyl-1-((R)-phenylalanyl)-N-(4-quinolylmethyl)-N-trifluoroacetyl-4-piperidinamine are reacted with 25 mg (0.640 mmol) of sodium borohydride in analogy to Example 2. The title compound ##STR56## is obtained as white foam. TLC: methylene chloride/methanol/conc. ammonia (350:50:1) Rf =0.49, FD-MS: M+ =478.
