Yield	Reaction Conditions	Operation in experiment
61%	With tetrakis(triphenylphosphine) palladium(0); sodium carbonate; In N,N-dimethyl-formamide; for 6h;Inert atmosphere; Reflux;	General procedure: To a solution of 2-bromobenzaldehyde (315 mul, 2.70 mmol) in DMF (20 ml) was added phenyl boronic acid (395 mg, 3.24 mmol), tetrakis-(triphenylphosphine)-palladium (31 mg, 0.027 mmol) and Na2CO3 (430 mg, 4.05 mmol). The result solution was stirred and refluxed for 6 h. After the reaction completed, the solution was cooled to room temperature, then partitioned between satd NaHCO3 and EtOAc, and the mixture was extracted with EtOAc. The organic layer was washed with brine, dried over MgSO4, and concentrated in vacuo. The residue was purified by silica gel column chromatography (hexane/diethyl ether = 8:1) to afford the product (369 mg, 2.03 mmol, 75% yield).
	With dichloro[1,1'-bis(di-t-butylphosphino)ferrocene]palladium(II); potassium carbonate; In water; acetonitrile; at 60℃;Inert atmosphere; Sealed vessel;	Typical preparative procedures were performed on 10.0 mmol scale using a Mettler-Toledo FlexiWeigh 30 automated solid handling unit to pre-weigh the aryl halide (10.0 mmol, 1.0 equiv), aryl boronic acid (12.0 mmol, 1.2 equiv) and Pd-118 (65.2 mg, 0.1 mmol, 1.0 mol %). Acetonitrile (10.0 mL) was added, followed by K2CO3 added as a stock aqueous solution (10.0 mL water containing 2.07 g, 15.0 mmol, 1.5 equiv). NB. No internal standard was added for preparative reactions. Reaction mixtures were sealed under a N2 atmosphere and heated to 60 C with magnetic stirring. HPLC analysis showed that reactions using aryl bromides were complete within 1 h but that aryl chlorides typically required 24 h.After reaction mixtures had cooled to room temperature, stirring was stopped and the phases were allowed to separate. The lower aqueous phase was removed and discarded (cutting away any interfacial catalyst residues if present) and the acetonitrile phase concentrated to dryness to give typically a light to dark brown solid or dark-coloured gum. Solids were triturated with methanol (20 mL) for 1-2 h, then isolated by filtration, washed once or twice with methanol (4 mL each wash) and dried under vacuum. Oils were purified by flash silica gel chromatography as noted below. All isolated compounds gave 1H NMR data in agreement with published values. Literature data is given for mp values for comparison.

The tube was evacuated and backfilled with argon, and toluene (3 mL) and 2'-chloroacetophenone (0.13 mL, 1.0 mmol) were added through a rubber septum. The tube was sealed with a teflon screwcap, and the reaction mixture was heated to 65° C. with stirring until the starting aryl chloride had been completely consumed as judged by GC analysis. The reaction mixture was then diluted with ether (30 mL) and poured into a separatory funnel. The mixture was washed with water (20 mL), and the aqueous layer was extracted with ether (20 mL).

To this mixture was added dimethoxyethane (DME, 29 kg). The reaction contents were stirred to provide a solution, and the solution was then heated to 50 0C. To this solution was added a 4.4 M aqueous solution of sodium hydroxide (3.55 kg of NaOH in 19.0 kg of water, 5.0 eq) over a 20 minute period,Page 38 of 58Attorney Docket No. 2004658-1130 (AM102450) 426261 Iv2 EPO <DP n="40"/>maintaining a temperature of 50 + 5 0C.

The mixture was gradually heated to reflux ( to 80 0C) over a 15 minute period, and was then stirred at 80 + 20C for 18 hours. At that time, the reaction was cooled to room temperature (22 - 25 0C), the DME/water layers were separated, and the organic layer was concentrated under reduced pressure to obtain a brown oil. To this brown oil was added tert-butyl methyl ether (TBME) (15.0 kg) and water (12.0 kg).

IPA (2 X 8.0 kg) was then added to replace TBME and the IPA solution (8 +/- 2 L) was cooled to 0 to 10 0C to induce crystallization.

Based on the results of gas chromatography-mass spectroscopy (GCMS) analysis the reaction was not complete. Thus, 7 g more boronic acid, 1 g of K2CO3, and 0.6 g of Pd(PPh3)4 as catalyst was added, and the resulting mixture was degassed and refluxed under nitrogen for 14 h. The reaction mixture was then cooled down and the organic phase was separated, evaporated, and purified by column chromatography on silica gel, eluted with heptanes to yield 4-chloro-2,5-difluoro-2?-methoxy-1,1?-biphenyl (11.0 g, 82% yield) as yellow oil.

After cooling to room temperature, the reaction solution was extracted therefrom by using toluene. A water layer was removed therefrom, and an organic layer was cleaned by using saturated saline and dried by using MgSO4. MgSO4 was filtered and separated and the organic layer was concentrated. A crude product obtained therefrom was purified by silica gel column chromatography (mixed solvent of hexane and toluene was used in a development layer) to obtain Intermediate IM-1 (16.94 g, yield of 77%). (0394) Intermediate IM-1 was identified by observing the mass number m/z=299 as the molecular ion peak through FAB-MS.
