To a 10-mL sealed tube, which was purged and maintained with an inert atmosphere of nitrogen, was added a solution of 4-(1-(5-(5-amino-1,3,4-oxadiazol-2-yl)-4-cyclobutyl-2-ethylbenzoyl)piperidin-4-yl)benzonitrile (compound 215.7, 228 mg, 0.500 mmol, 1.00 equiv) in ethanol (5 mL). This was followed by the addition of potassium hydroxide (280 mg, 4.99 mmol, 10.0 equiv) in portions. The resulting solution was stirred for 5 h at 80° C. behind a blast shield. After cooling to ambient temperature, the reaction was then quenched by the addition of 15 mL of water and extracted with 2×20 mL of ethyl acetate. The combined organic layers were dried over anhydrous sodium sulfate and concentrated in vacuo. This resulted in 200 mg (80%) of 4-(1-(4-cyclobutyl-5-(5-ethoxy-4H-1,2,4-triazol-3-yl)-2-ethylbenzoyl)piperidin-4-yl)benzamide as a yellow solid.
