Heptane → 3-[4-(Trifluoromethyl)phenyl]propanal

Participants

Reaction Steps

In an inert atmosphere, 3-(4-trifluoromethyl-phenyl)-propan-1-ol (1.02 g, 5 mmol) was dissolved in DCM (10 ml) and slowly added to a suspension of PCC (1.61 g, 7.5 mmol) in anhydrous DCM (15 ml). Stirring was continued for 4 h at rt. Anhydrous heptane (10 ml) was added to the reaction mixture followed by filtration over a pad of silicagel (15 g). The filtrate was evaporated to give 850 mg of 3-(4-trifluoromethyl-phenyl)-propionaldehyde. LC-MS: tR=0.94 min; [M+H]+=no ionisation.
