実験手順

197 mg (0.70 mmol) of 3,5-dibromobenzoic acid (prepared according to J. Organometallic Chem. 215, 281 (1981)) are reacted in analogy to Example 2a first with 2 ml (27 mmol) of thionyl chloride and subsequently with 200 mg (0.468 mmol) of (2R*,4S*)-2-benzyl-N-(4-quinolylmethyl)-N-trifluoroacetyl-4-piperidinamine and 130 μl (0.936 mmol) of triethylamine to give the title compound (168 mg, 52%). TLC: methylene chloride/methanol/conc. ammonia (700:50:1) Rf =0.60, FD-MS: M+ =687, 689, 691.
