Triethylamine → N-(4-Bromo-2-ethyl-benzyl)-methanesulfonamide

Participants

Reaction Steps

To 4-bromo-2-ethyl-benzylamine (650 mg, 3 mmol) and triethylamine (500 μL, 3.6 mmol) in dichloromethane (5 mL) at room temperature was added methanesulfonyl chloride (283 μL, 3.6 mmol). The solution was stirred 1 h, diluted in water and extracted with ethyl acetate. The organic layer was washed with saturated sodium bicarbonate, then saturated sodium chloride, dried (Na2SO4), filtered, and concentrated in vacuo to an off-white solid (880 mg, 100%). 1H NMR (300 MHz, CDCl3): δ ppm 1.25 (t, J=7.54 Hz, 3H) 2.69 (q, J=7.54 Hz, 2H) 2.90 (s, 3H) 4.27-4.31 (m, 2H) 4.40-4.50 (m, 1H) 7.21 (d, J=8.10 Hz, 1H) 7.32-7.40 (m, 2H).
