合成路线1

Mesylate (I) is heated with L-prolinol (II) to furnish pyrrolidine derivative (III), which can be converted into (VII) by different ways: 1) Treatment of (III) with t-BuOK and reaction with 4-fluorobenzaldehyde (IV) in DMF. 2) Conversion of (III) into chloropiperidine derivative (V) by means of SOCl2 in benzene, followed by reaction with 4-hydroxyaldehyde (VI) and K2CO3 in DMF in and chromatographic separation. 3) Mitsunobu reaction between (III) and 4-hydroxyaldehyde (VI) by treatment with PPh3 and DEAD in THF, followed by chromatographic separation. Derivative (VII) is condensed with 2,4-thiazolidinedione (VIII) in toluene in the presence of piperidine and benzoic acid to afford (IX), which is finally converted into its maleate form by treatment with maleic acid in Et2O.
