Aqueous HCl (1 mL of a 1M solution) was added to ethyl (3-{4-[(diphenylmethylene)amino]phenyl}cyclohexyl)acetate (137 mg, 0.32 mmol) in EtOH (10 mL) with stirring. After 1 h the reaction mixture was basified with aqueous potassium carbonate (10 mL of a saturated solution and the mixture was extracted with Et2O (2×15 mL), washed with water (15 mL) and dried. Volatile material was removed by evaporation and the residue was purified by chromatography eluting with 0-35% EtOAc/isohexane to give the title compound (Intermediate 89) (40 mg, 48%) as a gum; MS m/e MH+ 262.
