Procedure

A solution of 3-(5-{2-[(2-methoxyethyl)amino]ethoxy}-1H-indol-2-yl)-2(1H)- quinolinone 2-1 (150 mg, 0.4 mmol), 2-methoxypyrimidine-5-carboxaldehyde (110 mg, 0.8 mmol) and sodium triacetoxyborohydride (168 mg, 0.8 mmol) in DCE (25 mL) was stirred under ambient conditions for 18 h. The reaction mixture was concentrated, and the residue was partitioned between EtOAc and saturated NaHCO3 solution. The organic layer was washed with brine, dried over MgSO4 and concentrated. The residue was suspended in ethyl ether with the aid of sonication, then filtered and air dried to provide 3-[5-(2-{(2-methoxyethyl)[(2-methoxy-5-pyrimidinyl)methyl]amino}ethoxy)-1H-indol-2-yl]-2(1H)-quinolinone (2-2) as a yellow solid. 1H NMR (300 MHz, CDCl3) δ11.05 (s, 1H), 9.60 (s, 1H), 8.53 (s, 2H), 8.33 (s, 1H), 7.68 (d, 1H, J=8 Hz), 7.52 (t, 1H, J=8 Hz), 7.34 (d, 1H, J=8 Hz), 7.27 (t, 1H, J=8 Hz), 7.22 (d, 1H, J=8 Hz), 7.05 (s, 1H), 6.96 (s, 1H), 6 J=8, 2 Hz), 4.13 (t, 2H, J=6 Hz), 4.01 (s, 3H), 3.80 (s, 2H), 3.53 (t, 2H, 3.34 (s, 3H), 3.01 (t, 2H, J=6 Hz), 2.84 (t, 2H, J=6 Hz).
