Diethyl Ether → 2-Ethoxy-6-pentadecyl benzaldehyde

Participants

Reaction Steps

To a 250 mL round bottom flask fitted with a reflux condenser, was added pyridinium chloro chromate (PCC) (16.1 g, 75 mmol) in anhydrous dichloromethane (100 mL). 2-Ethoxy-6-pentadecyl-benzyl alcohol (18.1 g, 50 mmol) in dichloromethane (10 mL) was added in one portion to the magnetically stirred solution. After 1.5 hr dry ether (100 mL) was added and the supernatant decanted from the black gum. The insoluble residue was washed thoroughly with diethyl ether (3×25 mL), where upon it became black granular solid. The organic solution was passed through a short pad of celite, and the solvent was removed by distillation to obtain brownish low melting solid (Yield: 15 g).
