실험 절차
1-(2-hydrazinopyrimidin-4-yl)ethanol (13a) was dissolved in ethanol (300 mL) and Raney-Ni (35 mL, 50% slurry in water) was added. The flask was flushed with argon, put under a hydrogen atmosphere (balloon) and stirred at room temperature overnight. The mixture was filtered and concentrated under vacuum to give a red oil that was dissolved in methanol and concentrated onto silica before being purified by silica flash chromatography (100% ethyl acetate to 20% methanol in ethyl acetate) to give the title compound (9.0 g) as an orange oil.
