合成路线2
该中间体在本合成路线中的序号:(IV)The intermediate carbamate (V) has been obtained as follows. The reaction of 4-bromo-3-methoxynitrobenzene (I) with CuCN in NMP at 150 C gives 2-methoxy-4-nitrobenzonitrile (II), which is reduced with H2 over Pd/C in ethyl acetate to yield 4-amino-2-methoxybenzonitrile (III). Finally, this compound is condensed with phenyl carbamate (IV) by means of NaHCO3 in ethyl acetate to afford the desired carbamate intermediate (V).
