Reaction Steps

A solution of 10-chloro-2-(1-isopropyl-1H-1,2,4-triazol-5-yl)-5,6-dihydroimidazo[1,2-d]pyrido[4,3-f][1,4]oxazepine (80.0 mg, 0.242 mmol), piperazin-2-one (48.4 mg, 0.484 mmol), XPhos (23.0 mg, 0.0484 mmol), and Sodium-tert-butoxide (46.5 mg, 0.484 mmol) in was heated in microwave at 125 C for 30 min. The reaction was filtered thru celite then rinsed with EtOAc. The filtrate was washed water, brine. The organic layer was dried Na2SO4, concentrated to give 307, analyzed by rHPLC. MS: (ESI+)=395.2. 1H NMR (500 MHz, DMSO) δ 8.06 (s, 1H), 8.03 (d, J=5.7 Hz, 2H), 7.93 (s, 1H), 7.59 (s, 1H), 5.72 (dt, J=13.1, 6.6 Hz, 1H), 4.62-4.52 (m, 2H), 4.51-4.39 (m, 2H), 3.94 (s, 2H), 3.73-3.62 (m, 2H), 3.37-3.30 (m, 2H), 1.51 (d, J=6.6 Hz, 6H).
