Procedure

Cyanoacetic acid (0.9 g., 0.01 mole) was dissolved in 6 ml. of dioxane and 1 ml. of water. In a 15 minute period, 4-cyclohexylmethylpiperidine (1.8 g., 0.01 mole) was added. After an additional 15 minutes, 37% aqueous formaldehyde (1.8 g., 0.02 mole) was dripped in over a two minute period. The reaction mixture was agitated twelve hours at 20°-25° C., extracted with 200 ml. of ether, water washed, dried over anhydrous sodium sulfate, filtered and stripped. A yield of 1.2 g. of high purity product was obtained as a residue.
