methyl 3-[4-(hydroxymethyl)phenyl]propanoate

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: A suspension of methyl 4-hydroxymethylhydrocinnamate (2.34 g) and manganese dioxide (21.0 g) in 40 ml dichloromethane was stirred at room temperature for 17 hours. Manganese dioxide was filtered off onto Celite. The filtrate was evaporated and dried under reduced pressure to give methyl 4-formylhydrocinnamate (2.11 g, 91%) as a colorless solid. Manganese dioxide was filtered off onto Celite The filtrate was evaporated dried under reduced pressure
