Step A To a mixture of 2-bromothiazole (826 mg, 4.99 mmol) and tetrakis(triphenylphosphine) palladium (0) (175 mg, 0.151 mmol) in 1,2-dimethoxyethane (20 mL) was added 2-formylbenzeneboronic acid (0.9017 g, 6.01 mmol) and 1 N aqueous NaHCO3 (8 mL). The resultant mixture was heated at reflux for 6 hrs. The reaction mixture was diluted with water and extracted with EtOAc (2*50 mL). The organic solution was dried over Na2SO4, filtered and concentrated. The crude product was purified by gradient flash chromatography (10% to 25% EtOAc in hexane) to yield 2-(2-thiazolyl)benzaldehyde as a white solid.

With tetrakis(triphenylphosphine) palladium(0); sodium carbonate; In ethanol; water; for 5h;Inert atmosphere; Reflux; General procedure: Ethanol (500 mE), boronic acid Ar2-B(OH)2 (92.7 mmol, 1.2 eq) and bromoarylaldehyde or bromoheteroarylaldehyde Br-Ar,--CHO (77.3 mmol) are introduced in succession into a 1 E flask under argon and at ambient temperature. The solution is degassed with argon for 15 minutes. Pd(PPh3)4 (1.78 g, 1.55 mmol) and Na2CO3 (92.7 mE of a 2M solution in H20, 185 mmol, 2.4 eq) are then introduced in a single portion. Afier the addition, the reaction mixture is heated at reflux for 5 hours. The mixture is then evaporated to dryness. The residue is taken up in DCM (1 E) and H20 (200 mE). After decantation, the aqueous phase is extracted with DCM (200 mE). The organic phases are combined and then washed with a saturated NaC1 solution (400 mE), dried over Mg504 and concentrated under reduced pressure. The residue is then purified by flash chromatography on silica gel. The expected product is obtained with yields of from 59 to 94%.
