반응 단계
161 g of 1-isopropyl-2-methoxy-1-pyrrolinium methyl sulfate are added dropwise, with stirring, to a solution of 43.8 g of dimethylamine in 283 ml of benzene. Subsequently, boiling under reflux is effected for 1.5 hours; the heavy phase is separated off and washed 4 times with, in each case, 50 ml of diethyl ether. After drying under a high vacuum, 154 g (91% of theory) of the title compound (as a reddish oil) are obtained.
