4-Hydroxybenzaldehyde → 4-[5-(3-Methyl-5-isoxazolyl)pentyloxy]benzaldehyde

Participants

Reaction Steps

A solution of 7.2 g of 4-hydroxybenzaldehyde, 14.6 g of 5-(5-bromopentyl)-3-methylisoxazole, 4 g of potassium hydroxide in 100 ml of acetonitrile was heated at reflux for 1.5 hours. The reaction mixture was cooled and filtered, the solvent removed, and the residue recrystallized from isopropyl acetate-hexane to give 10.8 g of 4-[5-(3-methyl-5-isoxazolyl)pentyloxy]benzaldehyde as a pale yellow powder.
