실험 절차

1-(3-Dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (0.201 g, 1.30 mmol) is added to 5,6-diamino-1-isobutyl-3-methyl-1H-pyrimidine-2,4-dione (0.223 g, 1.05 mmol)) and (6,7-dimethoxy-1-methyl-isoquinolin4-yl)-acetic acid (0.25 g, 0.96 mmol) in methanol (5 ml) and water (1 ml) and the mixture is stirred at ambient temperature for 16 hours. The methanol is evaporated and the resultant solid collected by filtration, taken into methanol (5 ml) and 5M aqueous sodium hydroxide (0.5 ml) is added. The reaction is heated to reflux for 1 hour, cooled to ambient temperature and evaporated. The residue is dissolved in water and extracted with dichloromethane, the combined organic extracts are dried over sodium sulfate and evaporated to afford 8-(6,7-dimethoxy-1-methyl-isoquinolin4-ylmethyl)-3-isobutyl-1-methyl-3,7-dihydro-purine-2,6-dione, M+ 437.
