Ethyl 2-(2-(2-hydroxyethyl)-3,5-dimethyl-4-(4-(pyrrolidin-1-ylsulfonyl)benzyl)-1H-pyrrol-1-yl)acetate (20 mg, 0.045 mmol) in THF (2.0 ml), MeOH (0.500 ml) and water (0.50 ml) was stirred and LiOH (4.27 mg, 0.178 mmol) was added. The resulting mixture was stirred at 25° C. for two hours. The solvent was then removed and water was added, followed by 1 N HCl. The solvent was again removed, MeOH was added, and the resulting solution purified by preparative HPLC to give 12 mg of a light blue solid (12 mg, 0.029 mmol, 64.0% yield). 1H NMR (400 MHz, CDCl3) δ (ppm) 7.63 (d, 2H), 7.19 (d, 2H), 4.57 (s, 2H), 3.76 (s, 2H), 3.66 (t, 2H), 3.18-3.15 (m, 4H), 2.76-2.73 (m, 4H), 2.03 (s, 3H), 1.78 (s, 3H), 1.70-1.66 (m, 4H).
