YieldReaction ConditionsOperation in experiment
55% With 2 mol% Pd/C; sodium carbonate In N,N-dimethyl-formamide at 140℃; for 144 h; Inert atmosphere aryl bromide (1 mmol), alkyne (3 mmol), Na2CO3 (3 mmol), Pd/C (2 mo lpercent) and DMF (2 mL) were introduced in a sealed tube. The reactor was placed under stirring in a preheated oil bath at 120 °C or 140 °C after being flushed by argon. The reaction completion was monitored by GC. After cooling to room temperature, the reaction mixture was filtered through a celite pad, which was washed with EtOAc (100 mL). The resulting organic layer was then washed with Na2CO3 (2 .x. 40 mL) and brine (40 mL). The organic layer was dried over Na2SO4 and the solvent was removed under reduced pressure. If necessary (for the silylated compounds), the crude product could be fully deprotected by treatment with HCl 1 M before being purified by flash chromatography on silica.
