실험 절차

A solution of 1.61 g. (0.012 mole) of sodium thiophenoxide and 2.42 g. (0.01 mole) of 6-bromo-3-nitroimidazo [1,2-a] pyridine in 10 ml. N-methylpyrolidinone is heated at 150° C. for 0.40 minutes under a nitrogen atmosphere. The cooled solution is poured onto 100 ml. of ice-water and the resultant suspension is extracted with ethyl acetate. The combined extracts are washed with saturated aqueous sodium chloride and dried over magnesium sulfate. Evaporation of the solvent to a small volume and dilution with N-hexane yields crystalline material. The solids are purified by chromatography on silica gel. Elution with methylene chloride yields pure 3-nitro 6-phenylthioimidazo [1,2-a] pyridine m.p. 108°-109° C.
