To a solution of 5-(3-bromo-1,2,4-thiadiazol-5-yl)-2-[(1-methylethyl)oxy]benzonitrile (D44) (630 mg), 2-{2-ethyl-3-[(E)-2-(methyloxy)ethenyl]phenyl}-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (560 mg) and tripotassium phosphate (1237 mg) in N,N-dimethylformamide (DMF) (5 mL) and water (1.25 mL) stirred under nitrogen was added Pd(Ph3P)4 (225 mg). The mixture was sealed and heated under microwave at 120° C. for 15 min. After cooling the reaction, the mixture was concentrated and purified by column chromatography to give 5-(3-{2-ethyl-3-[(E)-2-(methyloxy)ethenyl]phenyl}-1,2,4-thiadiazol-5-yl)-2-[(1-methylethyl)oxy]benzonitrile (D54) (670 mg) as a colorless oil. MS (ES): C23H23N3O2S requires 405. found 406.2 (M+H+).
