実験手順

Methanol (10 mL) was purged with ammonia gas for 10 min at 0° C. [2,6-dibromo-4-(6-bromo-benzo[b]naphtho[2,3-d]thiophen-11-yl)-phenoxy]-acetic acid, methyl ester (0.50 g, 0.787 mmol) was added and the vessel was sealed, warmed to room temperature and stirred for two days. The reaction mixture was concentrated, diluted with ether and filtered. The solid was boiled in ethyl acetate (8 mL), hot filtered and washed with ethyl acteate and pentane and dried in vacou to provide the title compound as an off white solid (0.22 g, 45%): mp 263-265° C.: NMR (DMSO-d6); δ8.29 (d, J=8 Hz, 1 H), 8.09 (d, J=8 Hz, 1 H), 7.88 (s, 2 H), 7.80 (ddd, J=8, 7, 1 Hz, 1 H), 7.67-7.51 (m, 5 H), 7.30 (ddd, J=8, 7, 1 Hz, 1 H), 6.71 (d, J=8 Hz, 1H), 4.56 (s, 2 H); MS (EI): [M+], 3 bromine isotope pattern, 617 (30%), 619 (90%) 621 (100%) 623 (40%); Anal. Calc. for C24H14Br3NO2S: C, 46.48, H, 2.28, N, 2.26. Found: C, 45.69, H, 2.02 , N, 2.14.
