Stirring was continued for 16h before diluting with ethyl acetate (200 ml), and ffitering the solution through a plug of celite. Concentration in vacuo was follwed by column chromatography (eluant ethyl acetate) to give N-hexyl 2-amino acetaldehyde dimethyl acetal (7.39 g, 78%) as a colourless oil.
