Participants

Reaction Steps

1.8 g of 2-(4-hydroxyphenoxy)methylquinoline, 2.2 g of 8-bromomethyl-2-carboethoxy-4-oxo-4H-1-benzopyran and 1.0 g of potassium carbonate are combined in 100 ml of acetone and refluxed for 18 hours. The mixture is cooled, diluted with ethylacetate and filtered. The filtrate is concentrated and the crude product purified by flash chromatography on silica gel in 5% ethanol in chloroform/hexane (1:1) to give 0.96 g 2-carboethoxy-8-(4- (quinolin-2-yl-methoxy)phenoxymethyl)-4-oxo-4H-1-benzopyran: m.p. 124°-27° C.
