Dimethylamine → (4-Benzenesulphonyl-6-bromopyridin-2-yl)-dimethylamine

Participants

Reaction Steps

0.113 g (0.0003 mol) of 4-benzenesulphonyl-2,6-dibromopyridine and 0.54 ml of 5.6 M dimethylamine in ethanol were stirred at room temperature in a mixture of 3 ml of ethanol and 3 ml of dioxan for 5 hrs. After removal of the solvent the residue was chromatographed on silica gel with ethyl acetate/hexane 1:10. There was obtained 0.09 g (88%) of (4-benzenesulphonyl-6-bromopyridin-2-yl) -dimethylamine as white crystals; m.p. 128-130° C.
