78% | With water; In ethanol; at 50 - 60℃; for 3.5h; | General procedure: Amberlyst A26 OH (0.11 g) was added to a suspension ofthe nitrile (1 mmol) in EtOH?H2O (0.5 mL). The reactionmixture was stirred at 50?60 °C, and the progress of thereaction was followed by TLC. After the completion ofreaction, the mixture was diluted with acetone or EtOAc andfiltered to remove the catalyst. The desired products wereisolated by evaporation of the EtOAc or addition of H2O and filtration of the precipitate. |

178 mg (92%) | With potassium fluoride;palladium diacetate; In tetrahydrofuran; | EXAMPLE 30 Synthesis of 2-cyanomethylbiphenyl An oven dried resealable Schlenk tube was evacuated and backfilled with argon and charged with palladium acetate (2.2 mg, 0.01 mmol, 1.0 mol percent), 2-(di-tert-butylphosphino)biphenyl (6.0 mg, 0.020 mmol, 2.0 mol percent), phenylboron dihydroxide (183 mg. 1.5 mmol), and potassium fluoride (174 mg, 3.0 mmol). The tube was evacuated and backfilled with argon, and THF (1 mL) and 2-chlorobenzyl cyanide (152 mg, 1.0 mmol) were added through a rubber septum. The tube was sealed with a teflon screwcap, and the reaction mixture was stirred at room temperature until the starting aryl chloride had been completely consumed as judged by GC analysis. The reaction mixture was then diluted with ether (30 mL) and poured into a separatory funnel. The mixture was washed with 1.0 M NaOH (20 mL), and the aqueous layer was extracted with ether (20 mL). The combined organic layers were washed with brine (20 mL), dried over anhydrous magnesium sulfate, filtered, and concentrated. The crude material was purified by flash chromatography on silica gel to afford 178 mg (92percent) of the title compound. |

34% | With potassium phosphate; In dimethyl sulfoxide; at 130℃; for 24h;Inert atmosphere; | General procedure: A flask was equipped with a magnetic stir bar and charged with 1Hpyrrole-2-carbaldehyde (2a; 19.0 mg, 0.2 mmol, 1.0 equiv), 2-bromophenylacetonitrile(1a; 39.2 mg, 0.2 mmol, 1.0 equiv), and K3PO4(63.6 mg, 0.3 mmol, 1.5 equiv). The flask was evacuated and filledwith N2, and then anhydrous DMSO (2.0 mL) was introduced via a syringe.The flask was heated in a 130 °C oil bath for 24 h, at which timeTLC analysis [petroleum ether (bp 60?90 °C)?EtOAc, 10:1] indicatedcomplete consumption of 2a and 1a. The reaction mixture was cooledto r.t. and added to a sat. solution of NaCl (20 mL) and extracted withEtOAc (3 × 10 mL). The combined organic layers were dried (Na2SO4)and filtered. The filtrate was concentrated, and the residue was purified by column chromatography on SiO2 [petroleum ether (bp 60?90°C)?EtOAc, 10:1 to 30:1] to give 3ai; Yield: 19.9 mg (41percent); tan solid; mp 251.7?252.8 °C. |
