실험 절차

To a pyridine solution (1 mL) of 7-methyl-3-(3-trifluoromethylphenyl)-4,6,7,8-tetrahydro-1H-cinnolin-5-one (136.2 mg, 0.44 mmol) obtained in Example 65 was added p-toluenesulfonic acid hydrate (84 mg, 0.44 mmol) and stirred at room temperature for 3 days. The reaction liquid was concentrated, followed by purification of residue obtained with silica gel column chromatography (methylene chloride/methanol=30/1) to obtain an objective compound (89.0 mg, 66.1%).
