35% | With palladium diacetate; caesium carbonate; tert-butyl XPhos; In toluene; at 80℃; for 4h;Inert atmosphere; Sealed tube; | Palladium (II) acetate (0.08 g, 0.36 mmol) , caesium carbonate (2.23 g, 6.83 mmol), 2-di-tert-butylphosphino-2 ' , 4 ' , 6 ' - triisopropylbiphenyl (t-Butyl XPhos) (0.290 g, 0.68 mmol), compound 6 (0.59 g, 3.41 mmol), and 4 (0.88 g, 4.44 mmol) and toluene (30 mL) were combined and purged by a stream of argon for 3 minutes. The reaction was sealed and heated at 80 C for 4h. The mixture was filtered through a pad of Celite. The filtrate was concentrated under reduced pressure. The product was purified by flash chromatography on silica gel using 0-60% ethyl acetate in hexane. The product was recrystallized from diethyl ether (488 mg, 35%). mp : 132.0-133.0 C; 1H NMR (600MHz, CDC13) delta [ppm] : 10.22 (d, J=0.8 Hz, 1H) , 8.06 (d, J=8.4 Hz, 1H) , 7.44-7.41 (m, 3H) , 7.37-7.34 (m, 1H) , 7.32-7.30 (m, 2H) , 7.28 (d, J=7.5 Hz, 1H) , 7.26 (m, 1H) , 6.45 (dd, Jl=8.4 Hz, J2=0.8 Hz, 1H) , 5.52 (s, 2H) , 4.08 (3H), 2.28 (s, 3H) ; 13C NMR (151 MHz, DMSO-d6) delta [ppm] : 187.8, 166.6, 165.2, 143.2, 142.0, 140.5, 135.0, 134.8, 130.5, 129.5, 128.7, 128.3, 127.1, 125.7, 112.5, 103.9, 67.8, 54.1, 16.5; IR V (ATR cm-1): 3063, 2961, 2870, 1671, 1591, 1460, 1330, 1277; HRMS (ESI-TOF) Calcd for C21H19N03Na [M+Na]+ : 356.1263; found [M+Na]+: 356.1256. |
