Reaction Steps
A mixture of 20 gm (167 mMol) N,N-dimethyl-5-amino-2-pentanone, 14.5 gm (208 mMol) hydroxylamine hydrochloride, and 8.8 gm (83 mMol) sodium carbonate in 50 mL water was heated at reflux for 1.5 hours. After cooling to room temperature, the reaction mixture was extracted with dichloromethane. The organic extracts were combined, dried over sodium sulfate and concentrated under reduced pressure. The residual oil crystallized on standing at room temperature. The solid was washed with hexane to provide 12.8 gm (54%) of the desired oxime as a colorless solid in two crops.
