Reaction Conditions

Reaction Steps

196.9 ml morpholine, 500 ml toluol and 100 ml chloroform were stirred in a round-bottomed flask under N2 atmosphere and at 80° C. After one hour 100 g 4-chlorobutyronitrile was added dropwise within one hour. The reaction was stirred one day at 80° C. and another day at room temperature. The mixture was fritted and the residue was washed two times with ether. The filtrate was concentrated and finally distilleed under vacuum. The product fractions were collected at 95-100° C. and 1.2-0.89 Torr. The purity of the colourless oil was judged by gas chromatography and 1H-NMR.
