YieldReaction ConditionsOperation in experiment
60% With tetrakis(triphenylphosphine) palladium(0); sodium carbonate In tetrahydrofuran; water for 48h; Inert atmosphere; Schlenk technique; Reflux; 4-(2,5-dimethylthiophen-3-yl)-2-(2-hydroxyphenyl)benzothiazole (THBT) Under nitrogen atmosphere, HBT-Br (153 mg, 0.5 mmol), Na2CO3 (1.06 g, 10 mmol),Pd(PPh3)4 (28.9 mg), and H2O (5 mL) were charged in a 100 mL flame dried Schlenk tube. 2(143mg, 0.6mmol) in THF (50 mL) was added by syringe. Next, the mixture was heated toreflux for 48 h and monitored by TLC. After HBT-Br was fully reacted, as confirmed by TLC,the reactionmixturewas cooled to roomtemperature andpoured in todistilledwater (60mL).Themixturewas stirredfor 30m, then itwas extractedwithdichloromethane (25mL×3). Theorganic phase was combined and washed with brine (75 mL).Next, the solventwas dehydratedover anhydrous MgSO4 and evaporated in a vacuum. The residue was purified by silica gel(200-300 mesh) column chromatography with hexane and afforded THBT (168 mg, 60%).Mp: 225-228°C; 1H NMR (400 MHz, CDCl3) δ: 8.00 (d, 1 H, J = 8.0 Hz), 7.90 (d, 1 H, J =8.0Hz), 7.68 (s, 1 H), 7.51 (t, 1 H, J = 8.0Hz), 7.40 (m, 3H), 7.14 (d, 1 H, J = 8.0Hz), 6.73(s, 1 H), 2.48 (s, 6H); 13C NMR (100 MHz, CDCl3) δ 169.3, 156.7, 151.9, 137.1, 135.9, 133.1,132.6, 131.5, 128.6, 128.2, 127.1, 126.8, 125.6, 122.2, 121.6, 117.8, 116.6, 15.2, 14.1.
