실험 절차

To a solution of 0.090 g (0.35 mmol) of (+/−)-9-amino-2-pyrimidin-4-yl-5,6,8,9-tetrahydro-7-oxa-1,4-a-diaza-benzocyclohepten-4-one in 3.5 ml of dichloromethane was added 0.030 mL (0.36 mmol) of 2-pyridine carboxaldehyde, 0.184 g (0.87 mmol) of sodium triacetoxyborohydride and few drops of glacial acetic acid. The reaction mixture was stirred at room temperature for 15 hours. The residue was dissolved in dichloromethane and a saturated aqueous solution of sodium carbonate, extracted with dichloromethane and washed with saturated aqueous solution of sodium chloride, dried over sodium sulfate and evaporated. A recrystallization in isopropanol gives 0.042 g (35%) of pure product.
