Yield: 87%

Reaction Conditions:

in dichloromethane at 60; for 3 h;Inert atmosphere;

Steps:

2
To a 500 mL flask were added 130 g of dichloromethane,(127.2 g, 1.0 mol) of propylpiperidine, (195 g, 1.0 mol) N-methyl-bis (fluorosulfonyl) amine,Under a nitrogen atmosphere,Heating up to 60 ,The reaction was stirred for 3 hours.Standing cooling,At a temperature of 120 ° C,Pressure under the conditions of 0.1Pa vacuum distillation,To remove excess reactants,The colorless liquid was collected and washed three times with 50 ml of methyl t-butyl ether,Then at a temperature of 70 ° C,Vacuum degree of 0.01MPa under the conditions of vacuum drying,To give colorless liquid N-propyl-N-methylpiperidine bis (fluorosulfonyl) imide salt in 87% yield.
