Procedure

To a mixture of 4-chloro-3-(6-cyano-4-methyl-pyridin-3-yl)-N-[2-(3-hydroxy-propoxy)-phenyl]-N-methyl-benzamide 9-1 (30 mg, 0.07 mmol) in acetonitile (0.25 mL) and dichloromethane (0.25 mL), a solution of sodium periodate (40 mg, 0.19 mmol) in water (0.4 mL) was added followed by ruthenium (III) chloride (2 mg, 0.0096 mmol). The mixture was stirred 15 min, diluted with MeOH, stirred for 15 min and filtered. The filtrate was purified by prep. LCMS to yield 3-(2-{[4-chloro-3-(6-cyano-4-methyl-pyridin-3-yl)-benzoyl]-methyl-amino}-phenoxy)-propionic acid 11-1. MS [M+H]+: 449.8; tR=6.76 min. (method 2)
