YieldReaction ConditionsOperation in experiment
96.7% tetrakis(triphenylphosphine) palladium(0); In N,N-dimethyl-formamide; at 90℃; for 2.0h; Synthesis of Intermediate (1)(1 )Molecular Weig ht: 241.01 Molecular Weig ht: 187.12[00627] In a 3-neck 100 mL round-bottomed flask, stirred solution of 3-bromo-5- (trif uoromethyl)phenol (2 g, 1 eq.) in DMF(25 mL, 25 Vol) was degassed. ZN(CN)2 (0.68 g, 0.7 eq.) and Pd[P(Ph)3]4 (1.9 g, 0.2 eq.) was added in reaction and heat at 90C for 2 h. Reaction completion was monitored on TLC using ethyl acetate: hexane (2:8) mobile phase. Reaction mixture was brought to room temperature and quenched into the ice-water slurry (200 mL) and compound was extracted in the ethyl acetate (50 mL x 3). Organic layer was washed with brine solution (50 mL x 3) followed by drying using anhydrous sodium sulphate. Organic layer was concentrated under reduced pressure to afford 1.5 g of crude compound which was purified by column chromatography using ethyl acetate and Hexane as mobile phase. Product was eluted in 6% ethyl acetate in Hexane to afford 1.5 g of pure compound. Yield (96.7 %). Mass: 187.9.
60% With tetrakis(triphenylphosphine) palladium(0); In N,N-dimethyl-formamide; at 100℃; for 4.0h;Inert atmosphere; To a solution of <strong>[1025718-84-6]3-bromo-5-trifluoromethylphenol</strong> (7.2 g, 30 mmol) in DMF (100 mL) was added Zn(CN)2 (3.51 g, 30 mmol) and Pd(PPh3)4 (3.5 g, 6 mmol). The resulting mixture was stirred at 100 C under nitrogen atmosphere for 4 hours. EtOAc (250 mL) was added and the mixture was washed with water (2 x 50 mL) and brine (100 mL) before it was dried over MgSO4 and concentrated under reduced pressure. The residue was purified by silica gel chromatography (20% EtOA in hexane) to give a cololess oil (3.36 g, 60%).
