Методика

Pyridine (101.28 g, 106.6 mL 1281.79 mmol) was added to a solution of N,O-dimethylhydroxylamine hydrochloride (50 g, 512.72 mmol) in DCM (800 mL) at 0° C. and stirring was continued for 15 min. Chlorobutyrylchloride (72.29 g, 512.72 mmol) was then added to this mixture and was stirred continuously at 0° C. for 2 h. The reaction mixture was diluted with DCM and the organic layer was washed with water followed by brine. The organic layer was separated; dried over anhydrous sodium sulphate and concentrated under reduced pressure to afford 79 g of the title compound as a pale brown liquid.
