Reaction Steps

A mixture of (E)-3-(4-pyrrolidin-2-yl-phenyl)-acrylic acid methyl ester (5.52 g, 20.6 mmol), 3-butynyl p-toluenesulfonate (4.55 mL, 24.7 mmol) and potassium carbonate (5.98 g, 43.3 mmol) in acetonitrile (15 mL) was heated at 65° C. for 9 h. After cooled to room temperature, the reaction mixture was filtered, concentrated, and purified via silica gel column chromatography, and the residue was recrystallized from heptane to provide (E)-3-[4-(1-but-3-ynyl-pyrrolidin-2-yl)-phenyl]-acrylic acid methyl ester (3.68 g, 63% yield). LCMS (m/z): 284.2 (M+1).
