Versuchsvorschrift

A mixture of 21 parts of N-(2-chloro-5-nitrophenyl)-N'-(3-hydroxypropyl)thiourea, 10 parts of potassium carbonate and 180 parts of N,N-dimethylformamide is stirred and refluxed for 30 minutes. After cooling, 300 parts of water are added and the product is allowed to crystallize. It is filtered off and washed with water, yielding 13.3 parts (72.2%) of 3-[(5-nitro-2-benzothiazolyl)amino]-1-propanol; mp. 140°-144° C.
