Reaction Steps

Diethyl(methyl)-1,3-cyclohexanediamine, as a mixture of its 2,4-diethyl-6-methyl- and 4,6-diethyl-2-methyl-isomers (3.0 g), Pt(S)/C (0.4 g), Amberlyst-15 (0.4 g), and methyl ethyl ketone (45 g) were charged into a 100 mL metal autoclave at 22° C. The closed autoclave was purged 3 times with 125 psig (9.63×105 Pa) of H2 at 22° C. to remove traces of air. The reaction mixture was then heated at 130° C. under 125 psig (9.63×105 Pa) of H2 for 6 hrs (until no further H2 uptake was observed). The product mixture was cooled to 22° C. and degassed. A diluted product sample was analyzed by GC (100° C. for 5 minutes at 10° C. per minute rate; final temperature, 270° C.). The GC data (normalization method) showed 100% conversion of diethyl(methyl)-1,3-cyclohexanediamine, and a 95-97% yield of N,N′-di-sec-butyl-[diethyl(methyl)-1,3-cyclohexanediamine].
