Reaction Conditions:

with lithium aluminium tetrahydride;nickel dichloride in tetrahydrofuran at 5 - 65; for 5 h;Solvent;Reagent/catalyst;Temperature;

Steps:

9
Reduction reaction: 70 g (0.5 mol) of N, N-diisopropylaminoacetonitrile and 500 ml of tetrahydrofuran were added to a 1000 ml three-necked flask, and the temperature of the system was lower than 5 ° C,Batch slowly joinLithium aluminum tetrahydrate (0.7 mol),Nickel chloride O.Olmol, the control temperature is not higher than 15 ° C, after the completion of natural heating to room temperature to continue stirring lh, and then heated to 65 ° C reaction 5h, stirring with water, filtered and concentrated to dry after atmospheric distillation, ~ 172 ° C fractions, to be N, N-diisopropylethylenediamine 60.3 g, colorless liquid, the yield of 83.7%, gas purity 98.4%.
