Reaction Steps

In a sealed tube, a mixture of 1.9 g (20.4 mmol) of 2-aminopyridine and 6.1 g (30.6 mmol) of 4-bromophenethylamine dissolved in butanol (10 ml) is heated at 230° C. for 1 hour by microwave. The mixture, cooled to room temperature, is poured into water (50 ml) and extracted with ethyl acetate (3×100 ml), and the combined organic phases are dried over sodium sulfate, filtered and concentrated. The residue is purified by flash chromatography on a column of silica gel (eluent: dichloromethane/ethyl acetate, from 0% to 50% ethyl acetate). 1.4 g of product are obtained in the form of a white powder. Yield: 24%. Melting point: 71° C. MH+: 278.1 (tr: 3.71 min., condition 1).
