合成路线1
该中间体在本合成路线中的序号：(I)3,5-Dichlorobenzoic acid (I) is reduced with LiAlH4 to give 3,5-dichlorobenzyl alcohol (II). The latter is selectively oxidized with MnO2, yielding 3,5-dichlorobenzaldehyde (III). The condensation of (III) with methylamine gives the corresponding imine (IV), which can be reduced to the benzylamine (V) either with LiAlH4 or NaBH4. The hydrochloride is precipitated with etheric HCl.
