Abstract

A two-step one-pot process for reacting glycolaldehyde with an aminating agent in the presence of a reactive organic fluid for instance a reactive solvent is provided. The first step comprises of contacting glycolaldehyde with an aminating agent in the presence of a reactive fluid for instance a reactive solvent under inert atmosphere to produce unsaturated intermediates, and reacting the reaction mixture obtained in step 1 with hydrogen in the presence of a supported hydrogenation catalyst in a second step.
