実験手順

To a solution of ethyl(3S)-3-(4-hydroxyphenyl)hex-4-ynate (0.350 g, 1.5 mmol) in acetonitrile (25 mL) is added potassium carbonate (0.621 g, 4.5 mmol) and 1′-[4-(bromomethyl)benzyl]spiro[indene-1,4′-piperidine] (0.77 g, 2.1 mmol). The reaction mixture is heated for 16 hours at 90° C. The mixture is concentrated, diluted with water, and extracted with EtOAc (2×200 mL). The combined extracts are washed with water (50 mL), brine (50 mL), dried over sodium sulfate, filtered, and concentrated to dryness to give the title compound (0.3 g, 38%). ESI/MS m/z 520 (M+H)+.
