Versuchsvorschrift

To a mixture of 3-(4′,5′-difluoro-2′-methoxybiphenyl-4-yloxymethyl)-4-fluorobenzoic acid (0.3 g, 0.77 mmol) and N-methyl-glycine ethyl ester hydrochloride (0.7 g, 4.5 mmol) in methylene chloride (40 mL) was added HOAT (0.2 g, 1.46 mmol), EDCI (0.3 g, 1.56 mmol) and triethylamine (1.4 mL, 10 mmol). The mixture was stirred at room temperature for 3 hrs and extracted with methylene chloride and dilute hydrochloric acid. The organic layer was dried and concentrated. The residue was purified through flash column chromatography (80 g silica gel, 5% to 60% ethyl acetate in hexanes over 25 minutes) to give amorphous material as {[3-(4′,5′-difluoro-2′-methoxy-biphenyl-4-yloxymethyl)-4-fluoro-benzoyl]-methyl-amino}-acetic acid ethyl ester (0.29 g, 77%).
