To a stirred solution of methyl 3-methyl-5-{[methyl(pentyl)amino]methyl}benzoate (120 mg, 0.46 mmol) in methanol (2 mL), tetrahydrofuran (1 mL), and water (1 mL) is added lithium hydroxide (191 mg, 4.6 mmol), and the reaction mixture stirred at room temperature for 2 h. The reaction mixture is concentrated under reduced pressure, dissolved in methylene chloride, filtered, and the filtrate concentrated under reduced pressure to provide the title compound. ESI MS m/z 250 [M+H]+.
