YieldReaction ConditionsOperation in experiment
28.6% With tetrakis(triphenylphosphine) palladium(0); potassium carbonate; In 1,4-dioxane; water; at 90.0℃; for 2.0h; To a RBF was added 2-bromo-1-fluoro-4-methoxybenzene (1.850 mL, 9.02 mmol, Oakwood), <strong>[328956-60-1]3-fluoro-5-formylphenylboronic acid</strong> (1667 mg, 9.93 mmol, Combi-blocks), tetrakis(triphenylphosphine)palladium (521 mg, 0.451 mmol) and potassium carbonate (3741 mg, 27.1 mmol). A condenser and septum was attached and 1,4-dioxane (24.100 mL) and water (6.03 mL) were added. The mixture was heated at 90 C. for 2 h, at which time the reaction mixture was diluted with water (50 mL) and extracted with EtOAc (2*50 mL). The organic extract was washed with brine (20 mL) and dried over MgSO4. The solution was filtered and concentrated. The residue was absorbed onto a plug of silica gel and purified by chromatography through a 50 g silica column, eluting with a gradient of 0% to 30% EtOAc in Heptane, to provide 2',5-difluoro-5'-methoxy-[1,1'-biphenyl]-3-carbaldehyde (640 mg, 2.58 mmol, 28.6% yield) as white solid. 1H NMR (400 MHz, DMSO-d6) delta 10.01-10.14 (m, 1H), 8.01 (q, J=1.56 Hz, 1H), 7.82 (tdd, J=1.41, 2.59, 9.76 Hz, 1H), 7.67-7.78 (m, 1H), 7.32 (dd, J=9.65, 10.42 Hz, 1H), 7.18 (dd, J=3.23, 6.46 Hz, 1H), 7.05 (td, J=3.57, 9.00 Hz, 1H) 3.83 (s, 3H).

N2 was bubbled through the reaction solution for 5 min and 1.0 mL water was added. The resulting mixture stirred at ambient temperature for 1 h and LCMS analysis showed complete converstion to the desired product. The reaction mixture was diluted with ethyl acetate and washed with water and brine. The organic layer was separated, dried with MgSO4 and concentrated. The residue obtained was purified by silica gel chromatography eluting with ethyl acetate/hexane (0?50%) to give 440 mg of the desired product as white solid. MS (M+H)+=484.4.

YieldReaction ConditionsOperation in experiment
With toluene-4-sulfonic acid; In toluene; at 90.0℃; for 4.0h; A mixture of <strong>[328956-60-1]3-fluoro-5-formylphenylboronic acid</strong> (1 g, 5.95 mmol) and pinacol 76-09-5 (2.8 g, 23.8 mmol) were dissolved in Toluene (20 mL). Then p- toluensulfonic acid monohydrate (0.057 g, 0.3 mmol) was added and the mixture was heated at 90C for 4h. The mixture was allowed to cool to room temperature. It was concentrated under vacuum to give 2-[3-fluoro-5-(4,4,5,5-tetramethyl-1,3- dioxolan-2-yl)phenyl]-4,4,5,5-tetramethyl-1,3,2-dioxaborolane as light yellow oil (crude material).
