Versuchsvorschrift

To a solution of 100 mg 4-(2-o-tolyl-chroman-6-yloxy)-cyclohexanone (0.30 mmol) in 2 ml of methanol and 0.15 ml of acetic acid at room temperature 124 mg (1,3,5-trimethyl-1H-pyrazol-4-yl-methyl)amine (0.89 mmol) and 56 mg of sodium cyanoborohydride (0.89 mmol) were added in one portion and stirring at room temperature was continued for 2 h. Volatile components were removed under reduced pressure and the resulting residue dissolved in dichloromethane. The organic layer was washed with aqueous 2N sodium hydroxide solution and saturated aqueous sodium chloride solution. The organic layer was dried with sodium sulfate and filtered, and the solvent removed under reduced pressure. The crude product was purified by reversed phase HPLC. 132 mg of the title compound were isolated.
