실험 절차

A solution of anhydrous aluminum chloride (6.21 g., 0.0466 mole) in 75 ml. of anhydrous ether is added dropwise to a solution of lithium aluminum hydride (1.77 g., 0.0466 mole) in 50 ml. of absolute ether while stirring.An atmosphere of nitrogen is maintained in the apparatus and all vents are protected with drying tubes during the reaction. A solution of 5-cyano-5H-dibenzo[a,d]cycloheptene (10.13 g., 0.0466 mole) in 250 ml. of absolute ether is added dropwise with stirring (occasional warming of thissolution may be necessary to prevent precipitation of the nitrile). The reaction mixture is stirred at 23-26° C. for 1 hour after the addition is complete. Water, 35 ml., then is added dropwise. Dilute sulfuric acid is added, causing precipitation of a white solid. The solid is collected, suspended in water and the mixture rendered strongly alkaline with sodium hydroxide solution. The filtrate also is rendered strongly alkaline and both mixtures, containing suspended solids are extracted separately with ether. Distillation of the ether from the combined extracts leaves a white solid residue, m.p. 95°-96.5° C., weighing 10.04 g. Recrystallization from hexane gives 8.71 g. of product, m.p. 97.5°-98.3° C. (sinters 97° C.). An analytical sample melts at 98-98.8° C. (sinters 97° C.).
