3-(2-hydroxyethylamino)butanoic acid

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: A solution of 86 g of crotonic acid (1 mole) and ethanolamine (1 mole) in pyridine (200 ml) was refluxed for 2-3 hours and subsequently cooled. The resulting product was filtered and recyrstallized to yield the title compound having a m.p. (melting point) of 178-180° C. (compound 1.1, List of Compounds). subsequently cooled The resulting product was filtered
