Procedure

To a mixture of EXAMPLE 127C (60 mg) in DMF (1 mL) was added 2,4,5-trichlorophenol (43 mg) and Cs2CO3 (500 mg). The mixture was stirred at room temperature overnight, diluted with ethyl acetate (150 mL), and washed with water and brine. After drying over Na2SO4, the combined organic layers were concentrated, and the concentrate was saponified with LiOH as described in EXAMPLE 65B. 1H NMR (300 MHz, DMSO-d6) δ 12.92 (m, 1H), 10.88 (s, 1H), 7.89 (s, 1H), 7.82 (m, 2H), 7.38 (s, 1H), 7.32 (d, 1H), 7.10 (m, 2H), 4.13 (t, 2H), 3.25 (t, 2H), 2.13 (m, 2H), 2.10 (s, 3H).
