Procedure

4-[(S)-2-Aminopropionyl]aminomethyl-N-{2-[4-(4-fluorobenzoyl)piperidino]ethyl}-N-(2-methoxyphenyl)benzamide (84.7 mg, 0.155 mmol) was dissolved in methanol (5 ml) and mixed with oxalic acid (28 mg, 0.311 mmol). After 5 minutes of stirring at room temperature, methanol was removed by evaporation, and the resulting amorphous residue was washed with acetone (5 ml) and collected by filtration to obtain 84 mg (85.1%) of the title compound in a colorless amorphous powder form.
