N-(2-溴-3-甲基苯基)-3,3-二甲基丁酰胺

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: To a slurry of NaH in THF at 0° C. was added a solution of N-(2-bromo-3-methylphenyl)-3,3-dimethylbutanamide (1.42 g, 5.00 mmol) in THF. After 20 min at 0° C., methyl iodide (342 μL, 5.50 mmol) was added and the reaction mixture was allowed to stir at RT for 1 h. Additional 200 mg NaH and 0.34 ml MeI were added and the reaction was allowed to stir for 5 min. Water and EtOAc were added to the mixture, and the organic phase was separated and dried over MgSO4. The solvent was removed under reduced pressure and the remaining residue was purified by flash column chromatography (0-20% EtOAc/hexanes). N-(2-bromo-3-methylphenyl)-N,3,3-trimethylbutanamide was isolated as a clear, colorless oil. to stir for 5 min the organic phase was separated dried over MgSO4 The solvent was removed under reduced pressure the remaining residue was purified by flash column chromatography (0-20% EtOAc/hexanes)
