A mixture of N-(5-bromo(1,3-thiazol-2-yl))(2-chlorophenyl)carboxamide (47, 25 mg, 0.08 mmol), 2-(5-chloro-2-methylbenzoxzzol-6-yl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (4) (29 mg, 0.1 mmol), [1,1′-bis(diphenylphosphino)ferrocene]palladium(II) chloride dichloromethane complex (1:1) (12 mg) and potassium phosphate (21 mg) in 1 ml DMF and 0.2 ml water was heated under Ar in microwave reactor at 150° C. for 30 min. The reaction mixture was worked up with EA/brine. Org. phase was concentrated and then subjected to prep HPLC purification to give 3.1 mg N-[5-(5-chloro-2-methybenzoxazol-6-yl)(1,3-thiazol-2-yl)](2-chlorophenyl)carboxamide (49) as pale brown solid (yield: 9.6%; purity>90%). LC-MS: calcd. for C18H11Cl2N3O2S: 405 (M+1).
