To a solution of 3-mercaptobenzoic acid (361 mg, 2.35 mmol) in dimethylformamide (15 mL) add sodium hydride (23 mg, 9.38 mmol) at 0° C., stir 10 min. Add 1-[4-(6-bromo-pyridin-2-ylmethoxy)-2-hydroxy-3-propyl-phenyl]-ethanone (854 mg, 2.35 mmol), heat to 100° C. for 6 hours. Cool to ambient temperature and add diethyl ether, collect the resulting red precipitate by filtration (290 mg). Purify by the residue by preparative LC (inject 110 mg) to yield the title compound as a white solid (50 mg, 0.12 mmol): 1H NMR (DMSO-d6) δ 0.88 (t, 3H), 1.50 (q, 2H), 2.55 (s, 3H), 2.61 (m, 2H), 5.25 (s, 2H), 6.65 (d, 1H), 6.97 (d, 1H), 7.26 (d, 1H), 7.62 (t, 1H), 7.76 (m, 1H), 7.83 (m, 1H), 8.02 (m, 1H), 8.07 (m, 1H), 12.85 (s, 1H), 13.25 (br s, 1H); MS (m/z): 436 (M−1).
