合成路线1
该中间体在本合成路线中的序号:(XI)The diketone (IV) can also be obtained as follows: the nitration of 5-hydroxy-3,4-dihydrocarbostyril (IX) with HNO3 in acetic acid - acetic anhydride gives 5-hydroxy-8-nitro-3,4-dihydrocarbostyril (X), which is reduced with H2 over Pd/C affording 5-hydroxy-8-amino-3,4-dihydrocarbostyril (Xl). Finally, this compound is oxidized with FeCl3 in aqueous HCl.
