Procedure

To a mixture of EXAMPLE 98D (75 mg) and morpholine (32 mg) in dichloromethane (2 mL) was added 1-ethyl-3-(3-(dimethylamino)propyl)carbodiimide hydrochloride (58 mg) and DMAP (38 mg). The mixture was stirred at room temperature overnight and concentrated. The concentrate was diluted with ethyl acetate (150 mL), washed with 5% HCl, water and brine and dried (Na2SO4), filtered and concentrated. The concentrate was dissolved in THF (4 mL), methanol (2 mL) and water (2 mL). LiOH.H2O (100 mg) was added to the mixture and the mixture was stirred overnight. The mixture was concentrated, the concentrate was acidified with 5% HCl and extracted with ethyl acetate. The extract was washed with brine and dried (Na2SO4), filtered and concentrated. The concentrate was purified by reverse phase HPLC (C-18, 30 to 100% acetonitrile/water/0.1% TFA). 1H NMR (300 MHz, DMSO-d6) δ 12.95 (m, 1H), 10.79 (s, 1H), 8.25 (m, 1H), 7.87 (m, 1H), 7.71 (d, 1H), 7.35-7.57 (m, 6H), 7.27 (s, 1H), 7.08 (m, 2H), 6.90 (d, 1H), 4.21 (t, 1H), 3.64 (m, 8H), 3.37 (t, 2H), 2.26 (t, 2H), 2.07 (s, 3H).
