Versuchsvorschrift

A solution of 106 mg (0.5 mmol) 4-o-tolyl-nicotinic acid in 5 ml dichloromethane and 2 drops N,N-dimethylformamide was stirred with 0.1 ml (1.4 mmol) thionyl chloride for 1.5 h at room temperature. The solvent was removed and the residue was taken up in 5 ml dichloromethane and 0.3 ml triethylamine. After the addition of 155 mg (0.55 mmol) (3,5-bis-trifluoromethyl-benzyl)-cyclopropyl-amine the mixture was stirred at room temperature for 1 h and washed twice with water. The organic layer was dried (magnesium sulfate) and evaporated. The crude oil was subjected to column chromatography to give 140 mg (58%) of the title compound as an oil.
