Reaction Steps

21 mg (0.09 mmol) of 8-formyl-2-methyl-4-oxo-4H-chromene-5-carbonitrile are dissolved with 14 mg (0.09 mmol) of isopropyl acetoacetate, 8 mg (0.09 mmol) of 3-aminocrotononitrile and 6 mg (0.09 mmol) of acetic acid in 2 ml of 2-propanol and heated under reflux under argon for 6 h. The solvent is removed in vacuo, and the residue is purified by preparative HPLC. 8.8 mg (22% of theory) of the title compound are obtained as a yellow solid.
