Reaction Steps

A solution of 1 g of 1-(tert-butoxycarbonyl)-2-ethoxycarbonylpiperidine-4-carboxaldehyde and 2g of formylmethylene-triphenylphosphoran in 16 ml of toluene is heated to 100° (bath) for 2 hours. The solution is cooled and purified by flash chromatography using ethyl acetate/hexane (25:75) to yield 1-(tert-butoxycarbonyl)-2-ethoxycarbonyl-piperidine-4-acrylaldehyde.
