Potassium Cyanide → 1091611-71-0

Participants

Reaction Steps

To a mixed liquid of 1.51 g of potassium cyanide and 70 ml of acetonitrile, 6.12 g of 1,4,7,10,13,16-hexaoxacyclooctadecane was added, followed by stirring for 2 hours. Thereafter, a solution of 5.00 g of tert-butyl 3-(chloromethyl)benzoate in 30 ml of acetonitrile was added thereto, followed by stirring at room temperature for 18 hours. The reaction solution was concentrated, diluted with diethyl ether-hexane (1:1), and then washed with water and a saturated aqueous sodium chloride solution. After drying over anhydrous magnesium sulfate, the solvent was evaporated, and the residue was purified by silica gel column chromatography (eluent: hexane-ethyl acetate) to obtain 3.86 g of tert-butyl 3-(cyanomethyl)benzoate as a colorless oily substance.
