(5,6,7,8-Tetrahydroisoquinolin-3-yl)methanol → 5,6,7,8-Tetrahydroisoquinoline-3-carbaldehyde

Participants

Reaction Steps

A solution of 5,6,7,8-tetrahydro-3-isoquinolinylmethanol (572 mg, 3.50 mmol) in (DCM) (10 ml) at rt under argon was treated with manganese dioxide (3.047 g, 35.0 mmol) and then stirred at rt for 2 h. The reaction mixture was then filtered through a thin pad of Kieselguhr, eluting with DCM (50 ml), the organic extracts were evaporated to give the crude product as a brown oil (435 mg, 77%).
