Reaction Steps

96 mg (0.56 mmol) of 4-chlorophenylacetic acid are reacted in analogy to Example 2j first with 58 μl (0.795 mmol) of thionyl chloride and subsequently with 200 mg (0.468 mmol) of (2R*,4S*)-2-benzyl-N-(4-quinolylmethyl)-N-trifluoroacetyl-4-piperidinamine to give the product. TLC: methylene chloride/methanol/conc. ammonia (700:50:1) Rf =0.39, FD-MS: M+ =580.
