3-(3',4'-Dimethoxyphenyl)-1-propanol → 3-(3,4-DIMETHOXY-PHENYL)-PROPIONALDEHYDE

Participants

Reaction Steps

A solution of 2.0 g (10.2 mmol) of the aldehyde prepared in step A in 40 ml CH2Cl2 is oxidised in the dark by the addition of 4.32 g (10.2 mmol) Dess-Marin periodinane. The reaction is complete after 30 minutes. The suspension formed is taken up into 50 ml CH2Cl2 and washed twice with sodium bicarbonate and 20% sodium thiosulphate solution. Concentration of the organic layer affords a beige crude product which is purified by chromatography (hexane/ethyl acetate) to yield a yellow oil.
