Reaction Steps

Following the procedure described in example 47§C, but starting from potassium carbonate (1.71 g), 4-[4-(3-chloropropoxy)phenyl]pyridine 1-oxide (1.09 g), (3S)-3-methylpiperidine mandelate (1.25 g) and N,N-dimethylformamide (20 mL), affords 19 mg of the crude base which is converted to the oxalate with oxalic acid to give 13 mg of (3S)-4-{4-[3-(3-methylpiperidin-1-yl)propoxy]-phenyl}pyridine 1-oxide, oxalate.
