Reaction Steps

A mixture of 4-chloro-3-(6-chloro-4-methyl-pyridin-3-yl)-N-(2-hydroxy-phenyl)-N-methyl-benzamide (108 mg, 0.28 mmol), bromo methylvalerate (60 μL, 0.42 mmol) and K2CO3 (116 mg, 0.84 mmol) in DMF (1 mL) was stirred at room temperature for 14 hrs. Ethyl acetate was added and the combined organic layers were washed with water, dried over MgSO4, then purified by silica gel column chromatography eluted with ethyl acetate/hexane (1/4) up to 1/3 to yield 5-(2-{[4-chloro-3-(6-chloro-4-methyl-pyridin-3-yl)-benzoyl]-methyl-amino}-phenoxy)-pentanoic acid methyl ester 12-1 (50 mg). MS [M+H]+: 501; tR=8.52 min. (method 1)
