Methanol → 3-(Isopropylamino)-N-methylpropanamide

温度

140 °C

Isopropylamine (Aldrich; 1.5 ml, 17.62 mmol) and methyl acrylamide (ABCR; 1.0 g, 11.75 mmol) were combined in methanol (10 ml). The mixture was heated in a microwave at 140° C. for 30 min. The reaction was repeated and the combined reaction mixtures were concentrated to remove excess amine. The residue was re-dissolved in methanol and absorbed onto an SCX column (50 g), washed with methanol and eluted with ammonia/methanol. Concentration of the product containing fractions gave the title compound as a colourless oil (3.2 g, 94%).
