Reaction Steps

In an autoclave, a mixture of serinol (10.6 g, 0.12 mol), 1,3-dihydroxyacetone (10.4 g, 0.12 mol), and Raney nickel (1 g, wet) in methanol (100 ml) was heated to 65° C. under 250 psi hydrogen pressure for 3 h. The autoclave was cooled to ambient temperature and depressurized. The resulting reaction mixture was filtered to remove the catalyst. The filtrate was evaporated under vacuum to remove ammonia and most of the water. The residue was dissolved in a 1:1 mixture of 2-butanol and tetrahydrofuran, treated with activated carbon, and evaporated to give the bis-adduct 2,2′-iminobis-1,3-propanediol as a viscous oil (15 g, 79%). Assay by GC: 99%.
