Reaction Steps

A mixture of aminoacetonitrile bisulphate (15.4 g, 0.1 mol) and 2-methylheptan-2-ol (13.0 g, 0.1 mol) in acetic acid (60 ml) was treated with concentrated sulphuric acid (12 ml) with the temperature held at 40°-45° C. After stirring for 1 hour the mixture was poured into ice-water (300 ml) and washed with ether (2×200 ml). The aqueous phase was basified with 10 N sodium hydroxide solution, extracted with ether (3×200 ml) and the combined extracts were dried over magnesium sulphate then distilled to give 2-amino-N-(1,1-dimethylhexyl)acetamide as a colourless oil, b.p. 104°-110° C. at 0.2 mm Hg.
