YieldReaction ConditionsOperation in experiment
92% With palladium bis[bis(diphenylphosphino)ferrocene] dichloride In water at 90℃; Inert atmosphere add (S) -6- bromo-1- (isobutyl) in 100mL three-necked flask - N - ((4,6Dimethyl-2-oxo-1,2-dihydropyridin-3-yl) methyl) -3-methyl-1 Hydrogen - indole carboxamide (365mg,0.82mmol), 2- (piperazin-1-yl) pyridine-5-boronic acid pinacol ester (309mg, 1.07mmol, 1.3eq), phosphoric acidPotassium (522mg, 2.46mmol, 3eq), water and 1,4-epoxy hexadecane solvent. Then, under a nitrogen blanketWas added [1,1'-bis (diphenylphosphino) ferrocene] dichloropalladium (II) dichloromethane complex (53.9mg,0.066 mmol), and reaction at 90 deg.] C, after purification to give the desired product 400mg (92percent yield
87% With potassium phosphate; dichloro(1,1'-bis(diphenylphosphanyl)ferrocene)palladium(II)*CH2Cl2 In 1,4-dioxane; water at 90℃; for 24 h; Inert atmosphere To a 30 mL flask were added 9 (697mg, 1.57 mmol), 1-(5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl), piperazine (590mg, 2.04 mmol, 1.3 equiv), 1,4-dioxane (29 mL), H2O (7mL) and K3PO4 (1g, 4.7 mmol, 3 equiv), and the mixture was degassed with the aid of dry nitrogen three times. PdCl2(dpf)-CH2Cl2 adduct (103mg, 0.13 mmol, 0.08 equiv) was then introduced into the reaction flask under a stream of nitrogen, and the whole reaction mixture was heated at 90°C for 24h. The cooled reaction mixture was concentrated in vacuo, and the residue was taken up into MeOH (26 mL) and filtered off via celite. The filtrate was evaporated to dryness in vacuo, and the crude product was purified by flash column chromatography (eluting with DCM/MeOH, 10:1) to afford the final product (720mg, 87percent yield) as gray powder. m.p. 186-188°C (decomposed); [α]25D -11° (c=0.1, MeOH) (Lit.11 [α]25D -13.3° (c=0.1, MeOH)). 1H NMR (500 MHz, DMSO-d6):δ0.75 (m, 3H), 1.37-1.44 (m, 4H), 1.75-1.87 (m, 2H), 2.11 (s, 3H), 2.25 (m,3H), 2.77-2.85 (m, 4H), 3.45 (m, 4H), 4.35 (d, J=5.3 Hz, 2H), 4.56-4.68 (m, 1H)5.87 (s,1H), 6.88 (d, J=8.8 Hz, 1H), 7.17 (d, J=1.5 Hz, 1H), 7.26 (s, 1H), 7.73 (d, J=1.3 Hz, 1H), 7.91 (dd, J=8.8 Hz, 1H), 8.16 (t, J=5.1 Hz, 1H), 8.50 (d, J=2.5 Hz, 1H); 13C NMR (125 MHz, DMSO-d6): δ11.6, 12.6, 19.1,19.9, 21.7, 30.4, 35.9, 46.3, 46.9, 52.4, 107.6, 108.2, 108.5, 110.6, 116.9,122.6, 123.8, 125.2, 126.6, 130.6, 131.5, 136.7, 138.6, 143.5, 146.4, 150.2,159.2, 164.0, 169.6; HRMS (ESI): m/zcalcd. for C31H39N6O2 [M+H]+527.3129, found 527.3129.
91 mg With dichloro(1,1'-bis(diphenylphosphanyl)ferrocene)palladium(II)*CH2Cl2; sodium carbonate In 1,2-dimethoxyethane; water at 140℃; for 0.166667 h; Inert atmosphere; Microwave irradiation To a 30 mL microwave vial were added (S)-6-bromo-1-(sec-butyl)-N-((4,6-dimethyl-2-oxo-1,2-dihydropyridin-3-yl)methyl)-3-methyl-1H-indole-4-carboxamide (100 mg, 0.225 mmol), 1-(5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyridin-2-yl)piperazine (85 mg, 0.293 mmol), 1,2-Dimethoxyethane (DME) (3 mL), water (1.000 mL) and sodium carbonate (0.338 mL, 0.675 mmol), and the mixture was degassed for 5 min by bubbling nitrogen. PdCl2(dppf)-CH2Cl2 adduct (14.70 mg, 0.018 mmol) was added and the tube was sealed. The mixture was irradiated (microwave) at 140° C. for 10 min. The mixture was concentrated and the residue was taken up into MeOH and filtered. The filtrate was purified using reverse-phase HPLC (eluent: 25percent ACN/H2O, 0.1percent NH4OH to 60percent ACN/H2O, 0.1percent NH4OH) to give 91 mg of product as off-white solid. 1H NMR (400 MHz, DMSO-d6) δ ppm 0.70-0.78 (m, 3H), 1.37-1.44 (m, 3H), 1.75-1.87 (m, 2H), 2.11 (s, 3H), 2.16 (s, 3H), 2.22-2.27 (m, 3H), 2.77-2.85 (m, 4H), 3.41-3.49 (m, 4H), 4.35 (d, J=5.31 Hz, 2H), 4.56-4.68 (m, 1H), 5.87 (s, 1H), 6.88 (d, J=8.84 Hz, 1H), 7.17 (d, J=1.52 Hz, 1H), 7.26 (s, 1H), 7.73 (d, J=1.26 Hz, 1H), 7.91 (dd, J=8.84, 2.53 Hz, 1H), 8.16 (t, J=5.05 Hz, 1H), 8.50 (d, J=2.53 Hz, 1H); LCMS: 527.8 (MH+).
