実験手順

To a solution of methyl 5-(4-(4-cyanophenyl)piperidine-1-carbonyl)-2-cyclobutyl-4-methylbenzoate (compound 230.3, 1.50 g, 3.60 mmol, 1.00 equiv) in methanol (10 mL) was added aqueous sodium hydroxide (577 mg, 14.4 mmol, in 5 mL water) dropwise at 0° C. The resulting solution was stirred for 2 h at 60° C. in an oil bath. After cooling to ambient temperature, the organic solvent was removed under reduced pressure. The pH of the remaining aqueous layer was adjusted to 3-4 with hydrogen chloride (aq., 2 M). The resulting solids were collected by filtration and dried in an oven under reduced pressure to yield 1.20 g (83%) of the title compound as a white solid. m/z (ES+) 403 (M+H)+.
