To a solution of 3-bromo-5-{3-chloro-4-[(1-methylethyl)oxy]phenyl}-1,2,4-thiadiazole (D43) (388 mg), 2-{2-ethyl-3-[(E)-2-(methyloxy)ethenyl]phenyl}-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (335 mg) and tripotassium phosphate (741 mg) in N,N-dimethylformamide (DMF) (10 mL) and water (1.000 mL) stirred under nitrogen was added Pd(Ph3P)4 (134 mg). The mixture was sealed and heated under microwave at 120° C. for 10 min. After cooling the reaction, the mixture was concentrated and purified by column chromatography to give 5-{3-chloro-4-[(1-methylethyl)oxy]phenyl}-3-{2-ethyl-3-[(E)-2-(methyloxy)ethenyl]phenyl}-1,2,4-thiadiazole (D51) (313 mg) as a colorless oil. MS (ES): C22H23ClN2O2S requires 414. found 415.1 (M+H+).
