Procedure
To a solution of methyl 4-[5-[N-(tert-butoxycarbonyl)-piperidin-4-yl]-1,3,4-thiadiazol-2-yl]benzoate (1.28 g) in dichloromethane (12 ml) was added trifluoroacetic acid (25 ml) at 0° C. and the reaction mixture was stirred for 1 hour at room temperature. The solvents were removed under reduced pressure. The precipitate was triturated with diisopropyl ether, collected by filtration, washed with diisopropyl ether and dried under reduced pressure to give 4-[5-(4-methoxycarbonylphenyl)-1,3,4-thiadiazol-2-yl]piperidinium trifluoroacetate (1.31 g).
