YieldReaction ConditionsOperation in experiment
7% With dichloro(1,1'-bis(diphenylphosphanyl)ferrocene)palladium(II)*CH2Cl2; caesium carbonate; In N,N-dimethyl-formamide; at 100℃; for 16h;Inert atmosphere; Prepared in a similar fashion as described in Example 22 except that the following conditions were used in Part B: 2-(2-methoxy-4-nitrophenyl)-4,4,5 ,5 -tetramethyl- 1,3 ,2-dioxaborolane (700 mg, 2.508 mmol), 2-bromo- 1,3 ,4-thiadiazole(414 mg, 2.508 mmol), cesium carbonate (1634 mg, 5.02 mmol), and DMF (12 mL)were combined. N2 was bubbled into the reaction mixture for 2 mi (1,1?-Bis(diphenylphosphino)ferrocene)-dichloropalladium(II) dichloromethane complex(206 mg, 0.25 1 mmol) was then added and the reaction mixture was stirred at 100 Cfor 16 h. The mixture was cooled to room temperature, and was filtered through apad of diatomaceous earth (Celite) with ethyl acetate rinsing. The filtrate was transferred to a separatory funnel containing saturated aqueous NaHCO3 solution (15 mL). The aqueous layer was extracted with ethyl acetate (3 x 15 mL). The combined organic layers were washed with brine (10 mL), dried over MgSO4,filtered, and concentrated. The residue was purified by column chromatography on silica gel (1% -* 3% MeOH in CH2C12) to afford 2-(2-methoxy-4-nitrophenyl)-1,3,4- thiadiazole (42 mg, 7% yield) as a light brown solid: LC/MS (ESI) m/e 238.2 ((M+H), calcd for C9H8N303S 238.0).
