4-二丙氨基丁氰

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: 30 g (0.178 mol) of 4-dipropylaminobutyronitrile (3) was charged in a 500 ml three-necked flask, 150 ml of ethanol and 90 ml of a 1N sodium hydroxide aqueous solution was added thereto, and the mixture was stirred. 3.0 g of(10 wt %) the Raney nickel prepared in Example 1 was slowly added to the solution. After replacing the atmosphere in the flask with nitrogen and then with hydrogen, the mixture was allowed to react at room temperature for seven days with stirring while using a hydrogen balloon. After confirming that the raw material content had decreased to 1% or less by GC, the reaction solution was filtered through celite and washed with 400 ml of ethanol. After concentrating the filtrate, the residue was dissolved in 400 ml of chloroform and extracted with 200 ml of water. The chloroform layer was washed with 400 ml of a saturated sodium chloride aqueous solution, dried over anhydrous sodium sulfate, and concentrated, thereby obtaining 27.8 g of a colorless oily substance (yield: 90%). The resulting substance was distilled under reduced pressure to obtain 20.5 g of 4-dipropylaminobutylamine (4) (yield: 66.7%, GC: 99%). to react at room temperature for seven days with stirring the reaction solution was filtered through celite washed with 400 ml of ethanol After concentrating the filtrate the residue was dissolved in 400 ml of chloroform extracted with 200 ml of water The chloroform layer was washed with 400 ml of a saturated sodium chloride aqueous solution dried over anhydrous sodium sulfate concentrated obtaining 27.8 g of a colorless oily substance (yield: 90%) The resulting substance was distilled under reduced pressure
