Reaction Steps

To a suspension of 2-bromo-5-{3-chloro-4-[(1-methylethyl)oxy]phenyl}-1,3,4-thiadiazole (D10) (0.5 g), 2-ethyl-3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzaldehyde (D5) (0.468 g) and tripotassium phosphate (0.795 g) in N,N-dimethylformamide (DMF) (10 mL) and Pd(Ph3P)4 (0.173 g). The reaction mixture was degassed and then the reaction vial was sealed and heated under microwave at 130° C. for 10 min. Water was then added to the reaction mixture. The mixture was extracted with EA. The combined organic solution was dried over anhydrous sodium sulphate. After filtration and concentration, the residue was purified by column chromatography to give 3-(5-{3-chloro-4-[(1-methylethyl)oxy]phenyl}-1,3,4-thiadiazol-2-yl)-2-ethylbenzaldehyde (D11) (164 mg). MS (ES): C20H19ClN2O2S requires 386. found 387.1 (M+H+).
