Reaction Steps
0.378 mol (60.2 ml) 3-oxo-heptanoic acid methylester, 400 ml 33% methylamine solution in ethanol and 40 ml water were stirred for 48 hours at 80° C. in a round-bottomed flask with a reflux condenser. After cooling off, the solvents were distilled off on a rotavap, the raw products were taken up in 200 ml water and 40 ml ethanol and set to about pH 3 with 40 ml 32% HCl. The reaction mixture was heated to 90° C. for 24 hours and then again concentrated to dryness in the rotavap. The raw product heated with 150 ml to reflux, filtrated hot and the filtrate was left to cool off. The product was filtrated off and dried in a vacuum drying cabinet at 50° C. 5.9 g of the title compound was obtained.
