Procedure

A mixture of 3-(2-{[4-chloro-3-(4-cyano-6-trifluoromethyl-pyridin-3-yl)-benzoyl]-methyl-amino}-phenoxy)-propionic acid 11-4 (500 mg, 0.95 mmol), carbonic acid 1-chloroethyl cyclohexyl ester (393 mg, 1.9 mmol), triethylamine (399 μL, 2.85 mmol), and NaI (142.5 mg, 0.95 mmol) in DMF (5 mL) were stirred at 60° C. for 1 day. Ethyl acetate was added and the mixture was washed with water and brine, dried over MgSO4, filtered and concentrated. The residue was purified via silica gel flash column chromatography eluting with 20% ethyl acetate in hexane to afford 3-(2-{[4-Chloro-3-(4-cyano-6-trifluoromethyl-pyridin-3-yl)-benzoyl]-methyl-amino}-phenoxy)-propionic acid 1-cyclohexyloxycarbonyloxy-ethyl ester 37-1. MS [M+H]+: 674.2; tR=35.7 min (method 5).
