실험 절차

7-Methyl-3-(3-trifluoromethylphenyl)-5,6,7,8-tetrahydrocinnolin-5-ol (10 mg, 0.03 mmol) obtained in Example 6 was dissolved in a mixed solvent of tetrahydrofuran and dichloromethane (0.5 mL. 0.5 mL), followed by adding N-ethyl-N′-(3-dimethylaminopropyl)carbodiimide (9 mg, 0.045 mmol), N,N-dimethylaminopyridine (catalytic amount) and N-(tert-butoxycarbonyl)-L-alanine (9 mg, 0.045 mmol) and stirring at room temperature over night. After completion of the reaction, the reaction liquid was concentrated and thus obtained residue was purified using silica gel column chromatography (hexane/ethyl acetate=1/1) to obtain an objective compound.
