合成路线1
该中间体在本合成路线中的序号:(I)Displacement of the 2-fluoro group in 2,3,6-trifluorobenzonitrile (I) with aqueous ammonia leads to 2-amino-3,6-difluorobenzonitrile (II). Addition of hydroxylamine to the nitrile (II) in the presence of NaOMe affords benzamidoxime (III). Subsequent catalytic hydrogenation of (III) over Raney nickel furnishes benzamidine (IV).
