A solution of methyl 1-{[3-(5-{3-chloro-4-[(1-methylethyl)oxy]phenyl}-1,3,4-thiadiazol-2-yl)-2-ethylphenyl]methyl}-3-azetidinecarboxylate (D13) (30.3 g, 62.3 mmol) in Tetrahydrofuran (THF) (200 mL), Ethanol (150 mL) and Water (60 mL) was added sodium hydroxide (4.99 g, 125 mmol). The reaction mixture was stirred at room temperature overnight. Then pH of the reaction mixture was adjusted with 6 N HCl until pH ˜2.0. White solid was precipitated. The organic solvent was removed in by rotary evaporator. The solid was collected through filtration. The solid was washed water (150 mL×3) and dried in vacuo to afford 1-{[3-(5-{3-chloro-4-[(1-methylethyl)oxy]phenyl}-1,3,4-thiadiazol-2-yl)-2-ethylphenyl]methyl}-3 azetidinecarboxylic acid (31 g), which was used for the following procedure without further purification.
