Abstract: The reaction of bicyclo[2.2.1]hept-5-en-2-yl isocyanate with fluoro- andchloro-substituted anilines was used to synthesize in a yield of 25–68% a seriesof 1,3-disubstituted ureas containing a lipophilic group in their structure. Thesynthesized ureas are promising as inhibitors of RNA virus replication and humansoluble epoxide hydrolase.
