Reaction Steps

A mixture of 28 parts of N-(2-chloro-5-nitrophenyl)N'-(2-hydroxyethyl)thiourea, 14.5 parts of potassium carbonate and 225 parts of N,N-dimethylformamide is stirred and refluxed for one hour. After cooling, 300 parts of water are added. The precipitated product is filtered off, washed with water and dried, yielding 20.5 parts (82%) of 2-[(5-nitro-2-benzothiazolyl)amino]ethanol; mp. 183.4° C.
