Reaction Steps

The product from Example 36B (114 mg, 0.2 mmol), 4-methoxybenzenesulfonamide (37 mg, 0.2 mmol), DMAP (25 mg, 0.2 mmol), and EDCI (78 mg, 0.4 mmol) were combined in THF (10 mL) at room temperature. After stirring overnight, the mixture was concentrated under reduced pressure and CH2Cl2 (20 mL) was added. The mixture was washed with water and the organic layer concentrated under reduced pressure. The residue was purified via HPLC to provide the title compounds. 1H (500 MHz; DMSO-d6) δ6.4-8.6 (m, br., 20H) 5.0 (m, 1H) 4.7 (m, 1H) 4.1 (m, 1H) 3.5 (br, 3H) 1.4-2.7 (m, 6H); MS (M+H)+735.
