2-Methylbenzaldehyde → HCID 19769730, compound

Participants

Reaction Steps

To a solution of potassium t-butoxide (8.5 g) in t-butanol (100 ml) was added a mixture of 2-methylbenzaldehyde (6.0 g) and diethyl succinate (12.0 g) and the mixture was refluxed for 3 hours. After the solvent was evaporated under reduced pressure, 10% sodium hydroxide solution (100 ml) was added to the resulting residue and the mixture was refluxed for 5 hours. The reaction mixture was acidified with hydrochloric acid under ice-cooling and the precipitated crystals were collected by filtration to give 3.6 g of (E)-2-methylbenzylidenesuccinic acid.
