실험 절차

1.38 g (5 mmol) of 2-(1-methoxy-naphth-4-yl)-imidazo[1,2-a]pyrimidine are suspended in 50 ml of methylene chloride, cooled to -40° C. and 1.15 ml (12 mmol) of boron tribromide are added dropwise with stirring. The mixture is then stirred for 14 hours at ambient temperature, 30 ml of ethanol are added and the mixture is stirred for a further 30 minutes. It is then concentrated to dryness in vacuo and the crude product thus obtained in purified by column chromatography.
