Pyridine → 3,7-Dimethyl-7-ethoxyoctanal

Participants

Reaction Steps

A mixture of 1.9 of 7-ethoxy-3,7-dimethyloctan-1-ol and 10 ml. of pyridine is added to a suspension of 8.0 g. of chromium trioxide in 100 ml. of pyridine with stirring under nitrogen. After about 4 hours at room temperature, the reaction is poured into saturated sodium bicarbonate and worked up with ether followed by washing with 2N NaOH, water, 10% HCl, water and brine and evaporated under reduced pressure to dryness and then filtered with hexane to yield 7-ethoxy-3,7-dimethyloctan-1-al.
