实验步骤: To a solution of methyl-3-(cyanomethyl)benzoate (4 grams, 0.023 mol, 1 molequivalent) in 5 ml dry THF, 2M LiBH4 in THF (60 ml, 5 molequivalents) and (MeO)3B (3 ml, 1 molequivalent) were added under nitrogen atmosphere. The reaction mixture was stirred and heated at 70-75° C. for 16-18 hours. After cooling, THF was evaporated, and 2NH2SO4 was added to the residue (to acidify the solution to pH of 1-2). The resulting solution was washed with ether and powdered K2CO3 was added to the aqueous phase until the pH reached 7. NaCl was then added and the solution was extracted with THF. The organic phase was dried over MgSO4 and the solvent was evaporated, to give a 2.3 grams (67%) of a pure product, which was used without purification. After cooling THF was evaporated 2NH2SO4 was added to the residue ( The resulting solution was washed with ether and powdered K2CO3 was added to the aqueous phase until the pH NaCl was then added the solution was extracted with THF The organic phase was dried over MgSO4 the solvent was evaporated

实验步骤: A mixture of methyl 3-(bromomethyl)benzoate (0.6 gram, 2.6 mmol), potassium cyanide (0.35 gram, 5.2 mmol) and 60 mg of 18-crown-6 in 6 ml acetonitrile was vigorously stirred at room temperature for 24 hours. The mixture was filtered, the filtrate concentrated to half volume, water was added to the remaining mixture and extraction was performed with dichloromethane. The organic phase was dried over MgSO4 and the solvent was evaporated, to give the product as a yellow liquid, which was used without purification. The mixture was filtered the filtrate concentrated to half volume, water was added to the remaining mixture and extraction The organic phase was dried over MgSO4 the solvent was evaporated
