실험 절차

To a solution of 0.8 g (3.4 mmol) 6-(N,N-dimethylamino-carbonyl)-8-hydroxy-2,3-dimethyl-imidazo[1,2-a]pyridine in 16 ml ethanol and 4 ml water are added 1.0 g (6.2 mmol) 1,2-epoxy-7-methoxy-indane and 0.48 ml triethylamine. After 4 h at 30° C., the mixture is cooled down and partitioned between di-chloromethane and saturated aqueous ammonium chloride. The organic layer is separated, dried over anhydrous magnesium sulphate and evaporated. Purification of the residue by column chromatography on silica gel using ethyl acetate:light petroleum ether:triethylamine (8:1:1) yields 0.26 g (19%) of the title compound as a colourless solid (m.p. 129° C.).
