반응 단계
A mixture of 5-[2-(4-methylimidazol-1-yl)-1-(thiazol-2-yl)ethoxy]-2-(4-fluorophenethyl)benzoic acid (0.4 g; 0.89 mM), L-methionine methyl ester hydrochloride (0.27 g, 1.35 mM) and DMAP (0.54 g, 4.43 mM) was stirred until solution and EDC (0.026 g, 1.35 mM) in dichloromethane was added and the mixture stirred for 18 hours. It was purified on silica using dichloromethane then methanol/dichloromethane (5:95) as eluant to give the title product (0.47 g, 89%) as a foam.
