Methylamine → (2-Bromo-6-nitrophenyl)methanamine

Participants

Reaction Steps

A solution of 3-bromo-2-fluoronitrobenzene (1 g) in THF (8.3 ml) is heated in the presence of N,N-diisopropylethylamine (690 μA) and of methylamine (2.54 ml) in a microwave reactor (105° C., 30 min). The reaction medium is concentrated and then taken up in ethyl acetate, and then washed with water and then with brine. The organic extracts are combined, dried over magnesium sulphate, filtered and evaporated under reduced pressure. (2-Bromo-6-nitrophenyl)methylamine (1 g) is isolated in the form of an orange solid, and is used as it is in the next stage.
