4-Hydroxybenzaldehyde → HCID 18925383, compound

Participants

Reaction Steps

Under a nitrogen atmosphere 1,3-di (t-butyl)-2-methoxy-5-bromomethylbenzene (6.26 g, 20 mmol) is then reacted with 4-hydroxybenzaldehyde (2.44 g, 20 mmol) and potassium carbonate (3.04 g) in 140 ml of methyl ethyl ketone. The reaction mixture is heated to reflux and maintained at this temperature for about 18 hours at which time the reaction mixture is cooled. The inorganics are removed by filtration and the filtrate is concentrated in vacuo. The concentrated reaction products are purified by silica gel chromatography to yield 5.8 grams (81%) of 4-[[3,5-di (t-butyl)-4-methoxyphenyl]methoxy]benzaldehyde.
