YieldReaction ConditionsOperation in experiment
94% With palladium diacetate; caesium carbonate; 2,2'-bis-(diphenylphosphino)-1,1'-binaphthyl; In toluene; at 120℃;Inert atmosphere; To a solution of bromide (or triflate) (1 equiv) in toluene (0.1 M) was added aniline (1.2 equiv), Cs2CO3 (1.4 equiv) BINAP (0.08 equiv), and Pd(OAc)2 (0.05 equiv) at room temperature. The reaction mixture was allowed to stir at 120 C for 4-48 h. Once the reaction appeared to be complete by consumption of the bromide (or triflate) by TLC analysis, the mixture was allowed to cool to room temperature, diluted with EtOAc, washed with 2M aq HCl (2x), brine, and dried over sodium sulfate. The solution was concentrated, loaded on silica gel, and purified by silica gel chromatography.
94% With palladium diacetate; caesium carbonate; 2,2'-bis-(diphenylphosphino)-1,1'-binaphthyl; In toluene; at 120℃; General procedure: ]To a solution of bromide (or triflate) (1 equiv) in toluene (0.1 M) was added aniline (1.2 equiv), Cs2CO3 (1.4 equiv) BINAP (0.08 equiv), and Pd(OAc)2 (0.05 equiv) at room temperature. The reaction mixture was allowed to stir at 120 C. for 4-48 h. Once the reaction appeared to be complete by consumption of the bromide (ortriflate) by TLC analysis, the mixture was allowed to cool to room temperature, dilutedwith EtOAc, washed with 2M aq HC1 (2x), brine, and dried over sodium sulfate. The solution was concentrated, loaded on silica gel, and purified by silica gel chromatography.Reaction of <strong>[618-89-3]methyl 3-bromobenzoate</strong> with aniline according to general procedure A provided methyl ester of Compound 3 as a yellow oil (94% yield). ‘H NMR (CDC13, 500 MHz): ö=7.73 (s, 1H), 7.56 (d, J=7.6 Hz, 1H), 7.22-7.35 (m, 4H), 7.10 (d, J=8.5 Hz, 2H), 7.00 (t, J=7.4 Hz, 1H), 5.81 (s,1H), 3.91 (s, 3H). ‘3C NMR (CDC13, 125 MHz): ö=167.3,143.9, 142.6,131.6, 129.7,129.6, 122.0,121.9, 121.7,118.7,118.4, 52.3.
82% With palladium diacetate; caesium carbonate; (R)-2,2'-dihydroxy-[1,1']-binaphthyl-3-carbaldehyde; In toluene; at 120℃; for 24h;Inert atmosphere; In a 25 mL round-bottomed flask, toluene (10 mL) was degassed with argon for 20 min. Under a flow of argon, Pd(OAc)2 (0.05 g, 0.23 mmol), BINAP (0.23 g, 0.37 mmol) and Cs2CO3 (2.12 mmol, 6.51 mmol) were added and left to stir for a further 20 min. To the mixture, methyl (3-bromobenzoate) 1 (1.01 g, 4.65 mmol) and aniline 2 (0.51 mL, 5.58 mmol) were added. The reaction was stirred at 120 C and monitored by thin layer chromatography (TLC) for 24 h. Upon completion, the reaction was cooled to room temperature and filtered through Celite, with hexane as the eluent, followed by concentration under reduced pressure. The residue was purified by flash column chromatography on silica eluting with hexane/ethyl acetate (90:10) (Rf 0.23) to afford 0.87 g (82%) of 3 as a pale yellow solid; M.p. 110-112 C (literature M.p. 110-111 C) [40]; 1H NMR (400 MHz/CDCl3)/ppm, δ = 3.90 (s, 3H,-COOCH3), 5.81 (s, 1H, -NH), 6.98 (app. t, 1H, app J = 8 Hz, CHparaC4H4-NH), 7.09 (app. d, 2H, CHparaC2H2metaC2H2ortho-NH), 7.23 (m, 1H, HN-CH-C(COOCH3)-CHCHCH-), 7.29 (m, 3H, C2H2ortho-HN-CH-C(COOCH3)-CHCHCH-), 7.57 (app. d, 1H, HN-CH-C(COOCH3)-CH), 7.72 (m, 1H, HN-CHC(COOCH3)); 13C NMR (100 MHz/CDCl3)/ppm, δ = 52.2, 118.2, 118.4, 121.5, 121.77, 121.80, 129.4, 129.3, 131.4, 142.4, 143.6, 167.1; Found [M+H]+ (C14H14NO2) m/z 228.1019 (Calc. 228.1025); IR (ATR) v/cm-1: 3358, 3030, 1694, 1578, 1294, 744.
