Yield: 85.8%

Reaction Conditions:

with nickel;sodium hydroxide in water at 70 - 80; under 15001.5 Torr; for 4 h;Inert atmosphere;Autoclave;Reagent/catalyst;Temperature;

Steps:

4 Preparation of bicyclopropylmethylamine by catalytic hydrogenation
In a 500 ml autoclave, 100 g of bicyclopropyl ketoxime, 6 g of Raney nickel, 350 ml of water and 10 g of sodium hydroxide were added.Then nitrogen was replaced three times, and hydrogen was introduced. Control reactor hydrogen pressure of 2Mpa, the temperature is 70-80 ,After 4 hours, the reaction was completed. Discharge, cooling, stirring, suction, remove Rennes nickel.And then extracted with dichloromethane 200ml three times, combined methylene chloride solution, distillation.Collect 100mmHg, 100-110 fractions, that is, product bicyclopropyl methylamine. A total of about 81 g of product was obtained in a yield of 85.8%.
