Reaction Steps

(27%) was prepared as follows, substituting ethyl 3-(4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl)propanoate for 4-(methoxycarbonyl)phenylboronic acid. (1E,4E)-2-amino-8-bromo-N,N-dipropyl-3H-benzo[b]azepine-4-carboxamide (75.0 mgs, 0.206 mmol), 4-(methoxycarbonyl)phenylboronic acid (55.6 mgs, 0.309 mmol, tetrakis(triphenylphosphine)palladium(0) (23.8 mgs, 0.021 mmol), 2M aqueous potassium carbonate (0.309 ml, 0.618 mmol) were combined in 2 mls of acetonitrile in a microwave reaction vial. This mixture was heated in a microwave to 100° C. for 30 minutes. The mixture was then diluted with EtOAc, washed twice with brine, dried over sodium sulfate, and concentrated under reduced pressure. Preparative thin layer chromatography (2×0.5 mm plates, 7% MeOH/DCM) was then used. 1H NMR (400 MHz, CDCl3) δ 7.57-7.60 (m, 2H), 7.49-7.51 (m, 1H), 7.25-7.35 (m, 4H), 6.84 (s, 1H), 5.22 (very broad singlet, 1H), 4.11-4.17 (m, 2H), 3.41-3.51 (m, 4H), 2.95-3.04 (m, 2H), 2.83 (s, 2H), 2.64-2.69 (m, 2H), 1.58-1.72 (m, 4H), 1.20-1.30 (m, 3H), 0.88-0.99 (m, 6H); m/z (APCI-pos) M+1=462.3.
