Reaction Steps

Hydroxylamine sulfate (27.575 g, 0.168 mol) is added to a stirred solution of 4,4-dimethyl-3-oxopentanenitrile (20 g; 0.160 mol) and sodium hydroxide (26.24 g; 0.656 mol) in water (160 mL). The mixture is heated at reflux for 2 hours, then allowed to cool to room temperature and extracted with methylene chloride. The combined organics are washed with water, dried (Na2SO4), filtered and concentrated in vacuo to afford title compound as a white solid. ESI m/z 141 [M+H]+
