95% With bis-triphenylphosphine-palladium(II) chloride; sodium carbonate In 1,2-dimethoxyethane; ethanol; water at 65℃; for 1 h; General procedure: 1.00 mmol arylhalide, 1.30 mmol furfural-boronic acid and 0.05 mmolBis(triphenylphosphine)palladium(II) dichloride were treated with 0.30 mLdimethoxyethane, 0.50 mL ethanol and 0.30 mL aqueous 2M sodium carbonate solution.The reaction was heated to 65°C for 1h or until the TLC showed no remaining startingmaterial. The mixture was evaporated and extracted three times with ethyl acetate. Thecombined organic layers were washed with brine, dried over MgSO4, filtered andconcentrated. The crude product was purified by column chromatography usinghexanes/ethyl acetate (9:1).

Stage #1: With sodium hydrogencarbonate In DMF (N,N-dimethyl-formamide) at 50℃; for 7 h;
Stage #2: With sodium tetrahydroborate In DMF (N,N-dimethyl-formamide) at 5℃; for 0.5 h;
EXAMPLE 1Pd Coupling Reaction and Reduction of Aldehyde 95.38 g (400 mmol) of p-chloroiodobenzene, 34.85 g (600 mmol) of ally alcohol, 0.089 g (0.4 mmol) of palladium acetate and 47.99 g (2,000 mmol) of sodium hydrogencarbonate, were added to 200 ml of dimethylformamide (DMF), followed by heating until the internal temperature of the suspension became 50° C. The heating was continued for 7 hours, and after confirming the formation of the aldehyde compound by gas chromatogram, the suspension was cooled to 5° C. Then, 4.54 g (120 mmol) of sodium borohydride was added, followed by stirring for 30 minutes. Then, 100 ml of a saturated ammonium chloride aqueous solution, 100 ml of water and 200 ml of toluene were added, followed by stirring for one hour. After removing insolubles by Celite filtration, liquid separation was carried out, and the water layer was extracted again with 200 ml of toluene. The tolune layers were put together, concentrated and then distilled (107° C./1 mmHg) to obtain 63.4 g (y 93percent) of 3-(p-chlorophenyl)-1-propanol {compound (1)} as a colorless oily substance. From the analysis by gas chromatography, this product was found to contain 6percent of the branched isomer.

Stage #1: With copper(l) iodide; caesium carbonate In tetrahydrofuran at 20℃; for 0.0833333 h; Inert atmosphere
Stage #2: at 35℃; Inert atmosphere
a)
(4-Chloro-phenyl)-propynoic acid ethyl ester (Va)
Under argon atmosphere, a four neck flask was charged with 1-chloro-4-iodo-benzene (130.0 g, 0.55 mol), bis(triphenylphosphine) palladium(II) chloride (7.57 g, 10.8 mmol, 2 mol percent), copper(I) iodide (4.19 g, 22.0 mmol, 4 mol percent) and dry THF (1.4 l).
At r.t., cesium carbonate (355.3 g, 1.09 mol, 2 eq.) was added over 5 min.
Afterwards propynoic acid ethyl ester (111.3 ml, 1.09 mol, 2 eq.) was added, and the reaction mixture was stirred overnight at 35° C.
An additional portion of propynoic acid ethyl ester (11.1 ml, 0.11 mol, 0.2 eq.) was added, and the reaction was stirred for another 3 h at 35° C.
The reaction mixture was evaporated to dryness, and the residue was taken up in toluene (0.5 l) and heptane (1 l).
The resulting suspension was stirred at 40° C. for 1 h and filtered over celite.
The filtrate was concentrated, and the product purified by silica gel filtration (toluene/heptane 1:2) to yield 72.6 g (61percent) of Va as a light yellow solid.
