4-Amino-2,2,6,6-tetramethylpiperidine → HCID 17015563, compound

Participants

Reaction Steps

156 g (1 mole) of 4-amino-2,2,6,6-tetramethylpiperidine and 79 g (0.5 mole) of 2,5-dimethylfuran-3-carbonyl chloride in 1 l of toluene are refluxed for 24 hours, after which the precipitate is filtered off, the toluene solution is extracted by shaking with NaHCO3 solution and water, and is dried and evaporated down, and the residue is recrystallized from cyclohexane to give a product of melting point 116°-118° C.
