実験手順

The 2-(hydroxymethyl)-4H-chromen-4-one was dissolved in 30 ml of anhydrous chloroform at room temperature, 1 ml of thionyl chloride was added to the solution, and reaction mixture was stirred at room temperature for 24 hours. The solvent was thereafter evaporated, and the obtained liquid was dissolved in anhydrous hexane, which was also evaporated again to give 2-(chloromethyl)-4H-chromen-4-one which was further reacted without purification.
