実験手順

Combine (S)-N-methyl-(2-phenylpent-4-enyl)amine (1.93 g, 11.0 mmol), acetone/water (4/1, 125 mL), and sodium bicarbonate (3.0 g, 35.5 mmol). Cool in an ice bath with vigorous stirring. Add portionwise, 2-methoxy-5-(1H-tetrazol-1-yl) benzoyl chloride (2.86 g, 11.8 mmol). After the addition is complete, warm to ambient temperature. After 1.5 hours, evaporate in vacuo to remove most of the acetone. Extract the evaporated reaction mixture with ethyl acetate. Extract the organic layer with a saturated aqueous sodium bicarbonate solution and then brine. Dry the organic layer over MgSO4, filter, and evaporate in vacuo to give a residue. Chromatograph the residue on silica gel eluting with ethyl acetate to give (S)-N-methyl-N-(2-phenylpent-4-enyl)-2-methoxy-5-(1H-tetrazol-1-yl) benzamide: Rf =0.35 (silica gel, ethyl acetate).
