N-(4-bromo-2-ethylphenyl)-N-methylmethanesulfonamide

反応条件: temp:0.00; pressure:0.00; stir:

反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: Methyl iodide (1.6 g, 0.0256M) was added to a mixture of N-(4-bromo-2-ethylphenyl)methanesulfonamide (4.77 g, 0.0171M) and potassium carbonate (3.5 g, 0.0256M) in dimethylformamide (50 ml) at room temperature under an atmosphere of nitrogen. The reaction mixture was stirred for a further 24 hrs after which time it was partitioned between diethylether (100 ml) and water (100 ml). The aqueous was extracted further with diethyl ether (2×100 ml). The combined organics were dried over magnesium sulfate, filtered and the solvent concentrated in vacuuo to afford the title compound as a brown oil (3.6 g). was partitioned between diethylether (100 ml) and water (100 ml) The aqueous was extracted further with diethyl ether (2×100 ml) The combined organics were dried over magnesium sulfate filtered the solvent concentrated in vacuuo
