Reaction Steps

In 2 l of benzene was dissolved 623 g of morpholine ethanol. The solution was stirred while maintaining its temperature below 35° C. with ice-cooling, followed by dropwise addition of 735 g of thionyl chloride in 500 ml of benzene. Upon completion of the dropping, the resultant mixture was refluxed with stirring for 4 hours. After cooling, the crystalline precipitate was collected to give 872.4 g (yield: 98.7%) of chloroethylmorpholine hydrochloride having a melting point of 180°-182° C.
