4-Cyano-4′-pentylbiphenyl Use and Manufacturing

Methods of Manufacturing

General procedure: To a flask containing Mg turnings (0.29 g, 12 mmol) was added1-bromo-4-methylbenzene (1.37 g, 8.0 mmol) in THF (8 mL) at room temperature. After being stirred for 2 h, DMF (1.3 mL, 12 mmol) was added to the reaction mixture. The obtained mixturewas stirred for 2 h at 0 ° C. Then, aq NH3 (7 mL, 28-30percent) and I2 (4.06 g, 16 mmol) were added to the reaction mixture. After beingstirred for 2 h at room temperature, the reaction mixture waspoured into satd aq Na2SO3 solution and was extracted with CHCl3 (3*30 mL). The organic layer was dried over Na2SO4 and filtered.After removal of the solvent, the residue was purified by shortcolumn chromatography on silica gel (eluent: hexane/ethylacetate=9:1, v/v) to provide pure 4-methyl-1-benzonitrile (0.77 g) in 82percent yield.
