Reaction Steps
To a solution of 2-(4-chloro-2-oxo-1,2-dihydro-pyridin-3-yl)-6-(1-methyl-piperidin-4-yl)-1H-1,3,6-triaza-s-indacene-5,7-dione (448.3 mg, 1.35 mmol) and (R)-1-amino-3-(2,4-dimethyl-phenoxy)-propan-2-ol (303.0 mg, 1.55 mmol) in EtOH (10 mL) was added Et3N (410 mg, 4.05 mmol). After it was heated at 100° C. for 14 h, the reaction mixture was concentrated under reduced pressure. The chromatography of the crude residue (150:10:1 CH2Cl2/MeOH/28% aqueous NH4OH) afforded the title compound (498 mg, 45%). 1H NMR (DMSO-d6) δ 1.60 (m, 2H), 1.95 (m, 2H), 2.18 (s, 3H, CH3), 2.18 (s, 3H, CH3), 2.21 (s, 3H, CH3), 2.39 (m, 2H), 2.90 (m, 2H), 3.57 (m, 1H), 3.71 (m, 1H), 3.90-4.08 (3H), 4.18 (m, 1H), 5.55 (d, J=6 Hz, 1H, NH), 6.22 (d, J=6 Hz, 1H), 6.83 (d, J=6 Hz, 1H), 6.92 (d, J=6 Hz, 1H), 6.97 (s, 1H), 7.39 (d, J=6 Hz, 1H), 7.64 (s, 1H), 8.09 (s, 1H), 10.96 (br s, 1H, NH), 11.31 (br s, 1H, NH); ESI-MS m/z 571.3 (MH+).
