A solution of methyl 7-[4-({[3-(2,6-dichlorophenyl)-5-(1-methylethyl)-4-isoxazolyl]methyl}oxy)phenyl]-2-naphthalenecarboxylate (0.126 g, 0.2 mmol) in tetrahydrofuran (2.0 mL) was placed in a microwave reaction tube. Methanol (1.0 mL) was added followed by 1 N sodium hydroxide (0.3 mL, 0.3 mmol). The tube was sealed and heated in a microwave reactor to 100° C. for 600 seconds. The solution was neutralized and concentrated. Water was added and the mixture was filtered. The resulting solid was dried in a vacuum oven at 45° C. with P2O5 to yield the title compound (0.082 g, 73.9% as 0.30 tetrahydrofuran) 1H NMR (DMSO-d6): δ 13.3-12.6 (broad s, approximately 1H), 8.61 (s, 1H), 8.29 (s, 1H), 8.02-7.87 (m, 4H), 7.68 (d, J=9 Hz, 2H), 7.62 (d, J=8 Hz, 2H), 7.54 (dd, J=7, 9 Hz, 1H), 6.91 (d, J=9 Hz, 2H), 4.86 (s, 2H), 3.44 (septet, J=7 Hz, overlapping H2O, 1H), 1.33 (d, J=7 Hz, 6H). HRMS C30H23NO4Cl2 m/z 532.1082, (M+H)+cal; 532.1087 (M+H)+Obs.
