Procedure

To a stirred solution of 2-(5-(N-(5-cyclopropyl-2-(4-fluorophenyl)-3-(methylcarbamoyl)benzofuran-6-yl)methylsulfonamido)-2-nitrophenyl)acetic acid (2.00 g, 3.44 mmol) in 10 mL of 1:1 DMF/MeOH was added 2 M TMS-diazomethane in hexane (0.786 g, 6.88 mmol) at 0° C. and reaction mixture stirred for 2 h. The reaction was diluted with water and extracted into EtOAc. The ethyl acetate solution was washed with water, dried over sodium sulfate and evaporated to dryness to give the title compound in 70% yield. 1H NMR (400 MHz, CHLOROFORM-d) δ ppm 8.04 (d, J=9.19 Hz, 1H) 7.88 (br. s., 0H) 7.80 (t, J=6.06 Hz, 2H) 7.46 (s, 1H) 7.44 (br. s., 1H) 7.28 (dd, J=9.18, 1.95 Hz, 1H) 7.08-7.18 (m, 3H) 6.13 (br. s., 1H) 3.88 (s, 2H) 3.62 (s, 3H) 3.29 (s, 3H) 2.93 (d, J=2.93 Hz, 3H) 2.88 (s, 2H) 2.79 (d, J=1.76 Hz, 1H) 1.82-1.93 (m, 1H) 0.67-0.98 (m, 3H) 0.49 (br. s., 1H).
