Procedure

A mixture of 1-benzoyl-3-cyclooctylthiourea (14.3 g, 49.1 mmol) and potassium carbonate (34.6 g, 250 mmol) in methanol (200 mL), water (100 mL), and THF (100 mL) was stirred at ambient temperature overnight. The low boiling solvents were removed in vacuo, and the residue was partitioned between EtOAc and water. The organic portion was washed with brine, and concentrated in vacuo. The title compound was obtained as a white solid after flash column chromatography (0 to 100% of ethyl acetate in hexanes). MS m/z: 187.1 (M+H)+.
