合成路线1
该中间体在本合成路线中的序号:(IV)Treatment of 4-iodo-N,N-dimethyl-1H-imidazole-1-sulfonamide (I) with EtMgBr and 3-nitrobenzaldehyde (II) in CH2Cl2 yields derivative (III), whose nitro moiety is reduced by hydrogenation over Pd/C in EtOAc to afford aminophenyl derivative (IV). Treatment of (IV) with Et3SiH in TFA provides aminobenzyl derivative (V), which is finally converted into the desired compound by treatment with pyridine and ethanesulfonyl chloride (VI) followed by reflux in HCl.
