Reaction Steps

A mixture of 15.8g of dimethylamine, 32g of isophorone, 2g of 5% Palladium on charcoal and 150cc of ethanol was placed in an autoclave. Hydrogen gas was added to increase the pressure to 500 psi. The reaction mixture was heated to 95° C. and kept with stirring at 95° C. for 1 hr. Hydrogen gas was added during the reaction, to maintain a pressure of 330-500 psi. After the mixture was allowed to cool to ambient temperature, the solvent and the water produced were removed under diminished pressure. Distillation yielded 35g of N,N-dimethyl-3,5,5-trimethylcyclohexylamine; b760 196°-198° C.; nuclear magnetic resonance spectrum, δ in ppm, 2.18 s, 6H; 2.15-1.00 m's, 8H; 1.17 s, 3H; 0.90 s and 0.88 d, 6H.
