N,N-bis(2-hydroxyethyl)-3-oxobutanamide

Conditions: temp:0.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: A solution of 52.53 g (0.50 mol) diethanolamine in 100 ml MeOH was added dropwise to a solution of 40.00 g (0.48) diketene in 100 ml MeOH at 0° C. After stirring for 1 hour at 0° C., no starting material was detected anymore by thin-layer chromatography. The reaction mixture was spun off and the residue was purified by means of column chromatography. 81.32 g of product was obtained as a slightly yellow oil. the residue was purified by means of column chromatography

Conditions: temp:0.01; pressure:0.00; stir:; See reaction.notes.procedure_details.
