Versuchsvorschrift

A mixture of 43 parts of N-(3-chloropropyl)-2-nitrobenzenamine 47.8 parts of 5-chloro-1,3-dihydro-1-(4-piperidinyl)-2H-benzimidazol-2-one, 30.3 parts of N,N-diethylethanamine and 180 parts of N,N-dimethylacetamide is stirred and heated for 6 hours at 100° C. The reaction mixture is cooled and poured onto 1500 parts of water. The precipitated product is filtered off, washed with water and with 2,2'-oxybispropane and dried, yielding 64 parts (78.3%) of 5-chloro-1,3-dihydro-1-{1-[3-(2-nitrophenylamino)propyl]-4-piperidinyl}-2H-benzimidazol-2-one; mp. 220° C.
