With potassium acetate; In water; dimethyl sulfoxide; ethyl acetate; toluene; | EXAMPLE 26 4-(2,4-Dichloro-5-methoxyanilino)-7-[3-(4-morholinylmethyl) phenyll-3-quinolinecarbonitrile To a dry flask under a nitrogen atmosphere was added 200 mg (0.78 mmol) of 4-(3-bromobenzyl) morpholine, 0.218 g (0.86 mmol) of bis(pinacolato) diboron, 230 mg (2.34 mmol) of potassium acetate, 5 mL of dimethylsulfoxide and 32 mg (0.04 mmol) of [1,1'-bis(diphenylphosphino) ferrocene]dichloropalladium(II), complex with dichloromethane. The reaction mixture was heated at 80 C. for 2 hours. After cooling, the mixture was partitioned between 20 mL of toluene, 40 mL of ethyl acetate and 40 mL of water. The layers were separated and the aqueous layer was further extracted with 30 mL of ethyl acetate. The organic layers were combined and washed with 4*40 mL water. After drying over magnesium sulfate, removal of the solvents gave crude 4-[3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl) benzyl]morpholine as a dark oil. |

An aqueous solution of potassium carbonate (2M, 0.414 mL) was added and the mixture was stirred for 18 h at 75 0C. After 4 further additions of 1,1 bis(di-tert- butylphosphino)ferrocene palladium dichloride the mixture was heated for a total of 48 h. The mixture was evaporated and ethyl acetate was added. The resulting dark brown mixture was purified by flash silica chromatography, eluting with 20% ethyl acetate in isohexane and then with 40% ethyl acetate in isohexane containing 0.5% triethylamine to give a colourless oil. Formic acid (2 mL) was added and the mixture was heated at 50 0C for 12 min. The cooled mixture was basified with 0.880 aqueous ammonia and extracted with ethyl acetate. The organic layer was washed with water, dried over sodium sulphate, filtered and the solvent was evaporated. The resulting oil was purified by preparative HPLC on a Waters X-Bridge column using a 95-5% gradient of aqueous 0.1% TFA in acetonitrile as eluent. The fractions containing the desired compound were evaporated to dryness to afford the title compound (0.054g) as a yellow oil.1H NMR (399.825 MHz, D2O) delta 7.82 (d, J = 7.9 Hz, IH), 7.77 (s, IH), 7.73 - 7.68 (m, 2H), 7.62 (t, J = 7.8 Hz, IH), 7.52 (d, J = 7.7 Hz, IH), 7.49 - 7.43 (m, 2H), 5.08 (t, J = 7.8 Hz, <n="156"/>IH), 4.45 (s, 2H), 4.11 (d, J = 12.3 Hz, 2H), 3.90 - 3.83 (m, IH), 3.79 (t, J = 12.3 Hz, 2H), 3.48 (d, J = 12.3 Hz, 3H), 3.43 - 3.18 (m, 4H), 3.02 (t, J = 21.7 Hz, IH), 2.16 - 2.04 (m, IH), 1.99 - 1.82 (m, 2H), 1.80 - 1.44 (m, 3H) m/z 433 [M+H]+ |

The organic solution was dried (MgSO4) and evaporated under reduced pressure to yield the crude product as a yellow oil, which was purified using MDAP. The resulting material was partitioned between saturated aqueous sodium bicarbonate solution and dichloromethane.
