Reaction Steps

To a suspension of compound 1g (di-HCl salt, 105 mg, 0.327 mmol) and compound 1j (162 mg, 0.36 mmol) in CH2Cl2 (2 mL) was added Et3N (0.09 mL, 0.65 mmol). The reaction was stirred room temperature overnight. To the reaction mixture was added water, and the resultant mixture was extracted with CH2Cl2. The organic layer was dried over Na2SO4 and concentrated. Purification by flash column chromatography (silica gel, 5% MeOH/EtOAc+0.5% TEA) gave compound 10 (136 m g). MS m/z (M+H+) 490, 492. 1H NMR (300 MHz, CDCl3): δ 7.90 (m, 1H), 7.54 (m, 1H), 7.31-7.28 (m, 2H), 6.96 (m, 1H), 4.42 (d, J=3 Hz, 2H), 4.31-4.16 (m, 3H), 3.96-3.68 (m, 4H), 3.53-3.40 (m, 3H), 2.83 (m, 2H), 2.12 (m, 1H), 1.84 (m, 1H).
