反応手順
2-(N,N-dimethylamino)ethyl 2-vinyl-1-cyanocyclopropane-1-carboxylate was prepared by reacting essentially equimolar amounts of ethyl 2-vinyl-1-cyanocyclopropane-1-carboxylate and N,N-dimethylaminoethanol. For the reaction, a small amount of sodium metal (1.13 wt. %) was reacted with the N,N-dimethylaminoethanol prior to the addition of the ethyl 2-vinyl-1-cyanocyclopropane-1-carboxylate. The reaction mixture was stirred for 35 minutes after which time gas chromatographic analysis indicated the reaction to be 70% complete. After workup of the reaction mixture, the crude product was vacuum distilled to obtain the 2-(N,N-dimethylamino)ethyl 2-vinyl-1-cyanocyclopropane-1-carboxylate (B.p. 97° C. at 0.015 mm Hg). The infrared spectrum was consistent with the structure.
