実験手順

To a solution of methyl 7-[4-({[5-cyclobutyl-3-(3,5-dichloro-4-pyridinyl)-4-isoxazolyl]methyl}oxy)phenyl]-3-isoquinolinecarboxylate (39 mg, 0.070 mmol) in 2:1 tetrahydrofuran:methanol (1.5 mL) was added 1 N sodium hydroxide (0.10 mL, 0.10 mmol). The solution was heated in a microwave reactor at 120° C. for 500 seconds. The solution was concentrated under a nitrogen stream and 1 N aqueous hydrochloric acid (0.10 mL, 0.10 mmol) was added. The solution was concentrated further under an nitrogen stream and water was added followed by ethyl acetate. A solid precipitated. The water layer was removed and ether was added and the solid was isolated by filtration. The solid was dried under a nitrogen stream at 45° C. to afford 7-[4-({[5-cyclobutyl-3-(3,5-dichloro-4-pyridinyl)-4-isoxazolyl]methyl}oxy)phenyl]-3-isoquinolinecarboxylic acid (23 mg, 60%). 1H-NMR (400 MHz, DMSO-d6) δ 9.39 (s, 1H), 8.81 (s, 2H), 8.60 (s, 1H), 8.43 (s, 1H), 8.25-8.10 (m, 2H), 7.75 (d, J=9 Hz, 2H), 6.89 (d, J=9 Hz, 2H), 4.93 (s, 2H), 4.08-3.99 (m, 1H), 2.50-2.40 (m, 4H), 2.15-2.05 (m, 1H), 2.00-1.90 (m, 1H). HRMS (ESI) C29H21Cl2N3O4 calculated: 546.0982 [M+H]+, found: 546.0981 [M+H]+.
