Reaction Steps

The mixture of crude 4-chloro-3-(1,7-dihydro-1,2,5,7-tetraaza-s-indacen-6-yl)-1H-pyridin-2-one hydrochloric acid salt (80 mg, 0.25 mmol), (S)-2-amino-1-(3-bromo-4-methoxy-phenyl)-ethanol hydrochloric acid salt (105 mg, 0.37 mmol), N-methyl morpholine (0.5 ml, excess), and acetonitrile (15 mL) was heated to 80° C. overnight and cooled to room temperature. After concentration in vacuo, the residue was purified by prep. HPLC to yield the titled compound (79 mg, 66%). 1H NMR (400 MHz, CD3OD) δ 8.13 (s, 1H), 7.85 (s, 1H), 7.69 (narrow d, J=2.0 Hz, 1H), 7.59 (s, 1H), 7.40 (dd, J=2.0, 8.5 Hz, 1H), 7.29 (d, J=7.6 Hz, 1H), 6.96 (d, J=8.5 Hz, 1H), 6.22 (d, J=7.6 Hz, 1H), 4.93 (m, 1H), 3.80 (s, 3H), 3.66 (d, J=6.0 Hz, 2H). LCMS (t=1.39 min), [M+H]+ 495.
