Reaction Steps

37.8 g (0.3 mole) of dimethyl sulfate and 26.2 g (0.2 mole) of N-α-ethoxyethyl-acetamide are simultaneously added dropwise to 100 ml of 50% strength sodium hydroxide solution at 10°-15° C., while stirring intensively. The mixture is subsequently stirred for 3 hours, residual dimethyl sulfate is decomposed by adding concentrated ammonia, the phases are separated in a separating funnel, the aqueous layer is extracted several times with toluene and, after stripping off the solvent, the residue is distilled in vacuo. 26.1 g (90% of theory) of N-α-ethoxyethyl-N-methylacetamide of boiling point24 90°-94° C. are obtained.
