合成路线1
该中间体在本合成路线中的序号：(XXIVb)Alkylation of 4’-hydroxy-3’-methoxyacetophenone (XVII) with benzyl bromide by means of K2CO3 in DMF gives benzyl ether (XVIII), which is reacted with fuming HNO3 and concentrated H2SO4 in cold CH2Cl2 to afford 4’-benzyloxy-5’-methoxy-2’-nitroacetophenone (XIX). After reduction of the nitro group of compound (XIX) using iron powder and ammonium formate in refluxing H2O/toluene, the resulting 2-aminoacetophenone derivative (XX) cyclizes with ethyl formate (XXI) in the presence of NaOEt in DME, providing 7-benzyloxy-6-methoxy-4-quinolinol (XXII). Finally, quinolinol (XXII) is treated with trifluoromethanesulfonyl chloride in the presence of DMAP and 2,6-lutidine in cold CH2Cl2 .
