2-Dimethylaminomethylpropenenitrile (1.1 g., 0.01 mole) was cooled to 10°-15° C. and to it was added dropwise 4-hydroxypiperidine (1.0 g., 0.01 mole). The evolution of heat is observed. The homogeneous mixture is allowed to stand 12 hours at 15°-20° C. Completion of addition reaction is determined using thin layer chromatography on silica gel with benzene-methyl alcohol (90:10) development. The appearance of a single spot and elimination of reactant spots indicate termination.
