実験手順
A mixture of 3-phenylamino-but-2-enoic acid ethyl ester (7 g, 34.1 mmol) and propynoic acid methyl ester (4.6 mL, 51.2 mmol) in MeOH (114 mL) was refluxed for 48 h. The solvent was evaporated, and the crude oil was purified by silica gel chromatography (0-20% EtOAc/hexanes) to give 5.88 g of the title compound as an orange oil. MS: (+) m/z 290.27 (M+1).
