Procedure

1000 g 3-methylbutanal are reacted in the presence of 100 g of a commercially available nickel containing carrier catalyst (containing about 52 to 53% by weight nickel and employing chromium (3)-oxide as activator) at 110° C with a mixture of ammonia and hydrogen (volume ratio 1:1) in a flask equipped as described in Example 1. The velocity of the gases is 160 l/h. Altogether, 240 l ammonia and 240 l hydrogen are introduced into the catalyst suspension over a reaction time of 3 hours. After termination of the reaction the catalyst is separated by filtration. 868 g 3-methylbutylidene-3-methylbutylamine are obtained.
