Reaction Steps

The starting material is prepared as follows: To the solution of 20 g of 1,4-benzodioxan-2-yl-acetonitrile in 200 ml of benzene is added dropwise 71 ml of a 1.6 N solution of diisobutyl aluminum hydride in benzene while stirring at 10°. After 6 hours 50 ml of methanol are added, followed by 200 ml of water. The organic layer is separated, dried and evaporated, to yield the 1,4-benzodioxan-2-yl-acetaldehyde.
