Reaction Steps

To a solution of 0.71 g of 4-hydroxy-3-[3-[3-(methoxycarbonylmethoxy)phenyl]-1-oxo-2-propenyl]-1,6-dimethyl-2(1H)-pyridinone in 5 ml of dimethylformamide was added 0.090 g of sodium hydride (60% oily), and this was stirred at room temperature for 1 hour. 0.46 g of paratoluenesulfonyl chloride was added thereto, this was stirred at room temperature for 4 hours, then, 0.60 g of propargylamine was added, and this was stirred at room temperature overnight. To the reaction solution was added water, the solvent was distilled off under reduced pressure, and the residue was subjected to silica gel column chromatography to obtain 0.080 g of 4-propargylamino-3-[3-[3-(methoxycarbonylmethoxy)phenyl]-1-oxo-2-propenyl]-1,6-dimethyl-2(1H)-pyridinone [Compound No. (13b)] as a yellow crystal.
