Versuchsvorschrift

A mixture of 2-(1-methoxycycloheptyl)-5-(trifluoromethyl)benzaldehyde (167 mg; 0.556 mmol) and 3,5-bistrifluoromethyl benzylamine (150 mg; 0.616 mmol) in toluene (4 mL) was heated at reflux for 16 hours, after which solvent was removed. Ethanol (4 mL) and sodium borohydride (31 mg; 0.819 mmol) were added to the residue. The resulting mixture was stirred at room temperature for 16 hours. Solvent was evaporated under reduced pressure. The residue was taken up in ethyl acetate and washed twice with water and dried over sodium sulfate and concentrated under reduced pressure. The residue was purified over a 12 g RediSep column (Teledyne Isco Inc., Lincoln Nebr.) (eluted with 5-25% ethyl acetate in heptane) to yield 194 mg (66.1% for 2 steps) of the title compound as a gum. MS (ES+): Calc: 527.4 Found: 528.4 (M+H).
