Reaction Steps

A mixture of 5-(4-fluorophenyl)-3-methyl-1,2,4-thiadiazole (0.012 mol), 1-[3-(trifluoromethyl)phenyl]-piperazine (0.014 mol) and sodium carbonate (0.024 mol) in DMF (10 ml) was stirred at 140° C. for 24 hours, then at 150° C. for 24 hours, cooled, poured out into ice water (200 ml) and stirred. The precipitate was filtered off, taken up in DCM, dried, filtered and the solvent was evaporated. The residue was crystallized from DIPE. The precipitate was filtered off and dried, yielding 2.5 g (52%) of 1-[4-(3-methyl-1,2,4-thiadiazol-5-yl)phenyl]-4-[3-(trifluoromethyl)phenyl]piperazine (compound 2).
