A mixture of methyl 4-cyclobutyl-5-(5-ethyl-1H-imidazol-2-yl)-2-methylbenzoate (compound 245.2, 200 mg, 0.600 mmol, 1.00 equiv, 90%) and sodium hydroxide (107 mg, 2.68 mmol, 4.00 equiv) in a solvent mixture of methanol and water (4/2 mL) was stirred for 3 h at 60° C. After cooling to ambient temperature, the pH was adjusted to 3-4 with hydrogen chloride (aq., 6 M). The resulting mixture was concentrated in vacuo to yield 150 mg of a white solid.
