Potassium Iodide → HCID 19913858, compound

Participants

Reaction Steps

0.78 g of 2-(4-chloromethylphenoxy)methylquinoline, 0.76 g of 2-carbopropoxy-6-chloro-5-hydroxy-4-oxo-4H-1-benzopyran and a catalytic amount of potassium iodide are combined in 50 ml of acetone and 2 ml of dimethylformamide, and refluxed for 19 hours. The crude solid obtained on cooling is purified by flash chromatography to give 2-carbopropoxy-6-chloro-5-(4-(quinolin-2-ylmethoxy)benzyloxy) 4-oxo-4H-1-benzopyran having an m.p. of 173°-74° C.
