Sodium Sulfite → HCID 18182360, compound

Participants

Reaction Steps

Under stirring in an ice bathe, 1.25 g of N-iodosuccinimide was added little by little to a mixture of 1.2 g of 2-benzyl-6-(4-ethoxycarbonylpiperidino)pyridine and 10 ml of N,N-dimethylformamide, followed by stirring as it was overnight. Sodium sulfite was added thereto, and the mixture was extracted with ethyl acetate-water. The organic phase was washed with water and brine, dried over anhydrous magnesium sulfate and evaporated. The residue was subjected to silica gel column chromatography and eluted with 1-5% ethyl acetate/hexane, to give 1.42 g of the target compound.
