Methyl 2-(1-(tert-butoxycarbonyl)-1,2,3,6-tetrahydropyridin-4-yl)pyrimidine-5-carboxylate → HCID 66589682, compound

Participants

Reaction Steps

Methyl 2-(1-(tert-butoxycarbonyl)-1,2,3,6-tetrahydropyridin-4-yl)pyrimidine-5-carboxylate (960 mg, 3.01 mmol) and palladium, 10% on carbon (96 mg, 0.09 mmol) in ethanol (10 ml) and ethyl acetate (40.0 ml) were stirred under an atmosphere of hydrogen at atmospheric pressure and ambient temperature for 18 h. The reaction mixture was filtered through celite, washing with methanol, ethyl acetate and dichloromethane and concentrated under reduced pressure to give methyl 2-(1-(tert-butoxycarbonyl)piperidin-4-yl)pyrimidine-5-carboxylate (966 mg, 100%) as a yellow oil, which crystallised on standing. This was used directly with no further purification.
