실험 절차

To the acid chloride of 2-(2-naphthyl)-3-methylbutanoic acid (2.5 mmol) in ether is added 1.3 ml of triethylamine followed by the cyano(6-phenoxy-2-pyridyl)methanol in 5 ml of ether, from part A above, over about 2 minutes. The reaction mixture is stirred for about 18 hours and then quenched with saturated aqueous sodium bicarbonate. The organic phase is washed with aqueous sodium bicarbonate, water and brine, dried over calcium sulfate and solvent evaporated. The crude product is chromatographed on a circular chromatograph eluting with 20% ether/hexane to give cyano(6-phenoxy-2-pyridyl)methyl 2-(2-naphthyl)-3-methylbutanoate, MS m/e 436 (M+).
