Reaction Steps
To a solution of 3-[4-(3-aminophenyl)-2,6-dimethylphenoxymethyl]-1-methylpiperidine (513 mg, 1.58 mmol) in dichloromethane at 0° C. was added pyridine (1.3 mL, 16 mmol) and acetic anhydride (0.75 mL, 8.0 mmol). The mixture was stirred overnight at a temperature range from 0° C. to room temperature, and diluted with water and ethyl acetate. The aqueous layer was extracted with dichloromethane (3×), and the organic layers were dried and concentrated. The residue was purified on silica gel, eluting with 10% methanol/dichloromethane containing 0.5% ammonium hydroxide, to give 3-[4-(3-acetylaminophenyl)-2,6-dimethylphenoxymethyl]-1-methylpiperidine (479 mg, 82%).
