YieldReaction ConditionsOperation in experiment
27% Step 1 : 4.0g (0.02 mol) of 3-Bromo-5-methoxy-aniline, 4.6 g (0.05 mol) of glycerol, 2.46g (0.02 mol) of nitrobenzene and 12 ml of 75percent sulfuric acid were stirred for 3 h at 150°C. After this dark solution was poured onto 100 g of crushed ice, 100 ml of ethylacetate (EtOAc) and 30 ml of 30percent solution of NaOH. After 1 hour brown solid was filtered off and the organic layer was separated. After filtering through Si02 and evaporation of solvent 7-bromo-5- methoxy-quinoline and 5-bromo-7-methoxy-quinoline were separated as mixture approximately 60:40 (total 3.5g, 74percent) This mixture was separated to individual 7-bromo-5- methoxy-quinoline and 5-bromo-7-methoxy-quinoline with column chromatography on silica-gel with benzene-EtOAc (3: 1) as eluent. Yield of pure 7-bromo-5-methoxy-quinoline was 950 mg (27percent from mixture).

7-methoxy-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)quinoline A solution of <strong>[1126824-44-9]5-bromo-7-methoxyquinoline</strong> (0.407 g, 1.71 mmol, OxChem, Wood Dale, Ill., USA), 4,4,4',4',5,5,5',5'-octamethyl-2,2'-bi(1,3,2-dioxaborolane) (0.912 g, 3.59 mmol), PdCl2(dppf) (0.051 g, 0.070 mmol), and potassium acetate (0.503 g, 5.13 mmol) in DMF (9 mL) was stirred at 90° C. for 1 h then at 100° C. for 45 min. The reaction mixture was diluted with EtOAc (100 mL), and washed with saturated, aqueous sodium bicarbonate (2*75 mL). The organic layer was separated, dried over anhydrous Na2SO4, and concentrated in vacuo. The crude product was adsorbed onto silica and purified via column chromatography (silica gel, 0-80percent heptane/EtOAc) to give 7-methoxy-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)quinoline. MS (ESI, +ve) m/z: 286.1 (M+1)+.
