Participants

Reaction Steps

To a mixture of N-methyl aniline (5 mL) and potassium carbonate (9.6 g) in 100 mL dichloromethane was added bromoacetyl bromide (8.1 mL) (exotherm). The mixture was stirred for 4.5h then water was added. The phases were separated and the organic layer was concentrated. The crude product was purified by silica gel chromatography eluting with 0-100% EtOAc/cyclohexane. The relevant fractions were combined and evaporated and the residue was taken up in dichloromethane and washed with water. The organic layer was stirred with another portion of water for a few minutes and then the layers were separated. Evaporation of the organic layer gave the sub-titled compound (10.2 g) as a straw coloured solid.
