合成路线1
该中间体在本合成路线中的序号：(IX)Reaction of aldehyde (III) with 2-fluorobenzyl alcohol (VIII) by means of triphenylphosphine and diethyl azodicarboxylate (DEAD) in THF furnishes 6-(2-fluorobenzyloxy)naphthalene-2-carbaldehyde (IX) , which is then reduced with NaBH4 in ethanol/THF to give the naphthalenemethanol derivative (X). Halogenation of (X) by means of iodide, triphenylphosphine and imidazole in THF yields the naphthylmethyl iodide derivative (XI), which is finally condensed with thiazolidine-2,4-dione (IV) by means of HMPA and butyl lithium in THF.
