The synthetic route is as follows., name: 4-Chloro-N-methoxy-N-methylbutanamide
Step B 3-Chloropropyl 3,5-dimethylphenyl ketone A solution of 10.2 mL (13.9 g; 72 mmol) 5-bromo-m-xylene in 200 mL of anhydrous tetrahydrofuran was stirred under nitrogen at -78 C. as 35.8 mL (84 mmol) of 2.5 M n-butyllithium in tetrahydrofuran was added dropwise. After 15 minutes at -78 C., a solution of 10.0 g (60 mmol) of 4-chloro-N-methoxy-N-methylbutyramide in 30 mL of anhydrous tetrahydrofuran was added dropwise over 25-30 minutes. The resulting solution was maintained at -78 C. for 45 minutes and then warmed briefly to room temperature. The reaction was quenched by addition of 40 mL of 2 N hydrochloric acid and then partitioned between ethyl acetate and water. The organic phase was washed with saturated aqueous sodium bicarbonate solution and then saturated aqueous sodium chloride solution. The organic solution was dried over sodium sulfate, filtered, and concentrated in vacuo. Flash chromatography of the residue afforded 8.91 g (70%) of an oil, which had satisfactory purity by 1 H NMR (CDCl3).
According to the analysis of related databases, 64214-66-0, the application of this compound in the production field has become more and more popular.
