The invention relates to processes for the preparation of 1,2-diamines, and to the use of these compounds as intermediates for the preparation of several pharmaceutically active compounds. More particularly, it relates to the preparation of 2-methyl-1,2-diaminopropane. The process involves reductive cyclization of 1, 1 -cyanoanilide followed by hydrolysis of the resultant imidazole derivative to get 1,2-diamine.
