Procedure

Ninety grams (96.8% purity, 0.854 mole) 1,3-diaminopentane, 60 g acetonitrile (1.46 moles) and 3 g Cr promoted Raney® cobalt catalyst were charged to a 300 ml autoclave described in Example 1. The mixture was stirred and heated at 90° C. and 650 psig pressure for 5 hours followed by cooling to 25° C. Analysis of the filtered product on a capillary GC column showed a 14% conversion of 1,3-diaminopentane and 96.2% yield of 2-methyl-4-ethylhexahydropyrimidine
