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. Condensation of this carbamate with amine (V) in the presence of Et3N in refluxing toluene furnished urea (IX) (1). Both sulfide groups of (IX) were finally oxidized to sulfone using meta-chloroperbenzoic acid in CH2Cl2.
