Versuchsvorschrift

A mixture of intermediate (25) (0.0027 mol) in methanol (20 ml) was hydrogenated for 24 hours at room temperature with palladium-on-carbon (0.04 g) as a catalyst. After uptake of hydrogen (1 equivalent), the catalyst was filtered off and the filtrate was evaporated, yielding 0.35 g of 3,4-dihydro-2H-pyrano[3,2-b]pyridine-3-methanol (intermediate 26).

Aufarbeitung

  1. customthe filtrate was evaporated
