Reaction Steps

To 4-{5-Chloro-4-(4-cyano-6-trifluoromethyl-pyridin-3-yl)-2-[(2-methoxy-phenyl)-methyl-carbamoyl]-phenoxy}-butyric acid in ethanol (1 mL), 10 drops of SOCl2 were added. The mixture was stirred at rt for 24 hrs. The crude was purified via reverse phase preparative LCMS to afford 4-{5-chloro-4-(4-cyano-6-trifluoromethyl-pyridin-3-yl)-2-[(2-methoxy-phenyl)-methyl-carbamoyl]-phenoxy}-butyric acid ethyl ester 43-1 (12.2 mg). MS: [M+H]+ 576.3; tR=6.33 min (method 3).
