Reaction Conditions

Reaction Steps

To a three-necked 100 ml flask equipped for reflux and fitted with a mechanical stirrer was added 5.0 ml (0.047 mol) of salicylaldehyde, 2.0 g (0.014 mol) of potassium carbonate, and 10.0 ml (0.085 mol) of trimethyl phosphate. The mixture was heated to 85° C. for two hours, then cooled to 50° C. and quenched with 20 ml of water. After two hours the mixture was extracted with 50 ml of methylene chloride, the extracts washed with dilute caustic and then water. The organic extracts were dried over anhydrous potassium carbonate then filtered and concentrated in vacuo to give 3.6 g (53%) of o-methoxybenzaldehyde.
