4-Hydroxybenzaldehyde → p-(Octyloxy)benzaldehyde

Participants

Reaction Steps

A mixture of 4-hydroxybenzaldehyde (10.0 g, 81.8 mmol), 1-bromooctane (15.8 mmol, 81.8 mmol), and K2CO3 (34.0 g, 0.25 mol) in DMF (150 mL) was heated to reflux for 8 hours. After cooling the reaction back down to room temperature, the reaction mixture was diluted in toluene and the organic layer was washed with 10% HCl, brine, and water. After concentrating in vacuo, the oil was purified by short silica gel plug (10% DCM in n-hexanes). Solvent was dried in vacuo to afford the 4-octyloxy benzaldehyde as a slightly colored oil.
