실험 절차

To a solution of methyl 7-[4-({[5-cyclopropyl-3-(2,6-dichlorophenyl)-4-isoxazolyl]methyl}oxy)phenyl]-3-isoquinolinecarboxylate (54 mg, 0.099 mmol) in 2:1 tetrahydrofuran:methanol (1.5 ml) was added 1 N sodium hydroxide (0.15 mL, 0.15 mmol). The solution was heated in a microwave reactor to 120° C. for 500 seconds. The solution was concentrated under a nitrogen stream and 1 N hydrochloric acid (0.15 mL, 0.15 mmol) was added. The solution was further concentrated under a nitrogen stream. Water and ethyl acetate were added and a solid precipitated that would not dissolve. The water layer was removed and the resulting mixture was washed twice with water. The organic solvents were removed under vacuum and the resulting solid was dried at 45° C. under a nitrogen stream to afford 7-[4-({[5-cyclopropyl-3-(2,6-dichlorophenyl)-4-isoxazolyl]methyl}oxy)phenyl]-3-isoquinolinecarboxylic acid (36 mg, 68%). 1H-NMR (400 MHz, DMSO-d6) δ 13.1 (br s, 1H), 9.39 (s, 1H), 8.60 (s, 1H), 8.43 (s, 1H), 8.22-8.13 (m, 2H), 7.75 (d, J=9 Hz, 2H), 7.61-7.51 (m, 3H), 6.96 (d, J=9 Hz, 2H), 4.94 (s, 2H), 2.51-2.45 (m, 1H), 1.12-1.13 (m, 4H). HRMS (ESI) C29H20Cl2N2O4 calculated: 531.0880 (M+H)+, found: 531.0872 (M+H)+.
