실험 절차

4-[(Diallylamino)carbonyl]-2,2,6,6-tetramethylpiperidine (58.0 grams; 0.219 mole) is slurried in 37% formaldehyde (98.6 mls) at room temperature and 95% formic acid (17.4 mls) is added thereto. The mixture is heated at reflux for 18 hours and the resulting two-phase reaction mixture is adjusted to pH 11-12 by adding 50% sodium hydroxide. The mixture is extracted with dichloromethane and the organic extracts are combined and evaporated to obtain a clear liquid which on distillation affords 58.3 grams of the desired product which boils at 118°-125° C. at 0.10-0.15 mm of mercury.
