Formaldehyde → HCID 14697377, compound

Participants

Reaction Steps

15 ml of ethanol saturated with potassium carbonate, 18 g of paraformaldehyde, 1.43 g of potassium carbonate and 51 g of acetonecyanohydrin were stirred at 25° C. for 2 h and then brought to pH 6 with 85% strength phosphoric acid. 75 ml of ethanol and 88 g of N-[2,2,6,6-tetramethyl-4-piperidinyl]pelargonamide were added, and the mixture was refluxed for 6.5 h. The reaction mixture was filtered, the filtrate was concentrated and the residue was recrystallized from n-heptane to give 82 g of N-[1-cyanomethyl-2,2,6,6-tetramethyl-4-piperidinyl]pelargonamide having a melting point of 68° C.
