실험 절차

2-(4-Chloro-phenyl)-2-hydroxy-N-[2-(3-methoxy-4-prop-2-ynyloxy-phenyl)-ethyl]-acetamide (2.6 g, 7.0 mmol) is dissolved in N,N-dimethylformamide (30 ml). Sodium hydride (0.18 g, 7.5 mmol) is added in portions at +5° C. The mixture is stirred for 30 minutes at room temperature. Subsequently iodomethane (1.1 g, 7.5 mmol) is added dropwise and the resulting mixture is stirred for 3 more hours at room temperature. The reaction mixture is poured on ice/water (200 ml) and extracted with ethyl acetate (2×200 ml). The combined organic layer is washed with brine (200 ml) and dried over magnesium sulfate. After evaporation of the solvent, the residue is purified by chromatography (ethyl acetate/hexane) to yield 2-(4-chloro-phenyl)-2-methoxy-N-[2-(3-methoxy-4-prop-2-ynyloxy-phenyl)-ethyl]-acetamide.
