실험 절차
To a solution of homopiperazine (3.5 g, 35 mmol) in ethanol (100 ml) at 40° C., was added portionwise 2-chloropyrimidine (2.0 g, 17.5 mmol). The mixture was stirred for 1 hour then concentrated in vacuo. The residue was dissolved in methylene chloride (75 ml) and washed with a saturated solution of sodium bicarbonate and brine. Layers were separated, and the organic layer was dried over magnesium sulfate and concentrated. The resulting residue was purified by flash chromatography and a semi-solid (1.0 g) was collected and used as is.
