Versuchsvorschrift

In ethanol (20 ml) was dissolved 0.629 g of 6-ethoxycarbonylamino-1-methylisoquinoline (Preparation Example 32), and 8 N sodium hydroxide aqueous solution (6.8 ml), followed by heating under reflux for 1.5 hours. After cooling as it was to room temperature, an aqueous saturated ammonium chloride was added thereto, followed by extracting with ethyl acetate. The extract was washed with brine, dried over anhydrous magnesium sulfate and the solvent was evaporated, to give the title compound (0.311 g, 72%) as pale yellow crystals.
