Reaction Steps
A mixture of Intermediate F (40 mg, 0.160 mmol), 6-bromoquinoline (33.4 mg, 0.160 mmol), xantphos (18.57 mg, 0.032 mmol), Pd2(dba)3 (14.69 mg, 0.016 mmol) and DIPEA (0.111 ml, 0.642 mmol) in DMF (5 ml) was bubbled with N2 for 15 min and then was heated to 120° C. for 5 h under MW radiation. The solvent was removed under reduced pressure. The residue was purified with by silica gel chromatography eluted with DCM/MeOH (from 100% to 90%) to afford the title compound as a brownish solid (20 mg, 29.8% yield). 1H-NMR (400 MHz, DMSO-d6) δ ppm 8.87 (s, 1H), 8.50 (s, 1H), 8.35 (s, 1H), 8.29 (d, 1H), 8.04 (m, 1H), 7.98 (d, 1H), 7.91 (d, 1H), 7.85 (d, 1H), 7.65 (d, 1H), 7.53 (m, 1H), 3.84 (s, 3H). LCMS (method B): [M+H]+=377, tR=1.95 min.
