Procedure
(2-{[4-Chloro-3-(6-chloro-4-methyl-pyridin-3-yl)-benzoyl]-methyl-amino}-phenoxy)-acetic acid methyl ester (10 mg, 0.02 mmol) was dissolved in THF (300 μL) and 1M LiOH (100 μL) was added. The mixture was stirred at room temperature until LCMS indicated that starting material was completely consumed. The mixture was diluted with EtOAc and acidified with 1 N HCl. The organic layer was concentrated, dissolved in MeOH and purified by prep LCMS to yield (2-{[4-chloro-3-(6-chloro-4-methyl-pyridin-3-yl)-benzoyl]-methyl-amino}-phenoxy)-acetic acid 4-1. MS [M+H]+: 445.0; tR=6.75 min, (method 2)
