Reaction Steps

A solution of 0.158 g (0.97 mmol) of 3-(1H-imidazol-4-yl)propylamine and of 0.154 g (0.97 mmol) of 2-chloro-5-nitropyridine in 10 ml of 2-propanol is brought to reflux for 21 h while stirring and evaporated under reduced pressure. The resulting residue is chromatographed on a column of silica gel, using a chloroform/methanol (1/1) mixture, to give the title compound in the form of a yellow oil. The latter is treated with oxalic acid in heated absolute ethanol to provide the oxalate salt which, after crystallization from 2-propanol, melts at 181°-182° C.
