실험 절차

The amine is dissolved in methanol (160 mL), triethylamine (1.45 g, 14.4 mmol) and 2-pyridinecarboxaldehyde (1.59 g, 14.8 mmol) are added, and the mixture is stirred overnight. Polymer supported borohydride (Aldrich, borohydride on Amberlite IRA-400, 2.5 mmol/g, 6.0 g, 14.8 mmol) is added and the mixture is stirred for an additional 24 hours. The resin is removed by filtration and the filtrate is concentrated in vacuo. The residue is dissolved in a small amount of ethyl acetate and triturated with hexane to yield (R)-6-methyl4′-trifluoromethylbiphenyl-2-carboxylic acid [2-(2-pyridylmethylamino)-indan-5-yl] amide as a solid. The solid is dissolved in ethanol (100 mL) and a saturated solution of HCl (g) in ethyl ether is added. The resulting solid is collected to yield (R)-6-methyl-4′-trifluoromethylbiphenyl-2-carboxylic acid [2-(2-pyridylmethylamino)-indan-5-yl] amide hydrochloride, m.p. 281-283° C.
