실험 절차
230 mg (0.63 mmol) of 1-(4-methoxyphenyl)-2-[(2-methyl-4-oxo-4H-chromen-8-yl)methylene]-butane-1,3-dione are heated with 90 mg (0.63 mmol) of n-propyl 3-aminocrotonate in 5 ml of 2-propanol under reflux overnight. The solvent is removed in vacuo, and the residue is purified by preparative HPLC. 74 mg (24% of theory) of the title compound are obtained.
