合成路线1
Condensation of 4-bromobenzaldehyde (I) with 4-fluorophenol (II) in the presence of K2CO3 in refluxing dimethylacetamide gave ether (III). Subsequent reductive amination of (III) with cycloheptylamine (IV) using ethanolic NaBH4 afforded secondary amine (V). Phenyl carbamate (VIII) was obtained by treatment of aminopyridine (VI) with phenyl chloroformate (VII) and dimethylaniline. Finally, condensation of this carbamate with amine (V) in the presence of Et3N in DMF at 100 C furnished the target urea.
