Dimethylformamide → n-Propyl-5-(3-(quinolin-2-ylmethyloxy)benzyloxy)benzoxazole-2-carboxylate

Participants

Reaction Steps

A mixture of 3.47 g of 2-((3-chloromethylphenoxy)methyl)quinoline, 2.7 g of n-propyl-5-hydroxybenzoxazole-2carboxylate, 1.69 g of potassium carbonate and 1 ml of dimethylformamide is refluxed in 50 ml of acetone for 41 hours. The mixture is concentrated in vacuo and the residue is dissolved in water. This solution is neutralized with diluted hydrochloric acid and the resulting solid is filtered off and purified by flash silica gel chromatography in propanol-dimethylformamide to give n-propyl-5-(3-(quinolin-2-ylmethyloxy)benzyloxy)-benzoxazole-2-carboxylate
