Reaction Steps
9-bromo-2-(1-isopropyl-3-methyl-1H-1,2,4-triazol-5-yl)-5,6-dihydrobenzo[f]imidazo[1,2-d][1,4]oxazepine 411 and ethyl 2-methyl-3-(4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazol-1-yl)propanoate were reacted under Suzuki palladium coupling conditions to give ethyl 3-(4-(2-(1-isopropyl-3-methyl-1H-1,2,4-triazol-5-yl)-5,6-dihydrobenzo[f]imidazo[1,2-d][1,4]oxazepin-9-yl)-1H-pyrazol-1-yl)-2-methylpropanoate LC/MS (ESI+): m/z 490 (M+H), which was hydrolyzed with lithium hydroxide in water then the corresponding acid was treated with ammonium chloride, HATU, diisopropylethylamine, and DMF to give 243. LC/MS (ESI+): m/z 461 (M+H). 1H NMR (500 MHz, DMSO) δ 8.35 (d, J=8.4, 1H), 8.15 (s, 1H), 7.95 (s, 1H), 7.86 (s, 1H), 7.36 (dd, J=8.4, 1.7, 2H), 7.25 (d, J=1.7, 1H), 6.83 (s, 1H), 5.82 (dt, J=13.2, 6.6, 1H), 4.51 (s, 4H), 4.30 (dd, J=13.5, 7.6, 1H), 4.02 (dd, J=13.5, 7.0, 1H), 2.91 (dd, J=14.3, 7.1, 1H), 2.25 (s, 3H), 1.47 (d, J=6.6, 5H), 1.01 (d, J=7.0, 3H)
