Reaction Steps
Triethylamine (0.544 g; 2.99 mmole) and thereafter methanesulfonyl chloride (0.392 g; 2.99 mmole) were added to a solution of 3-{4-[2-(4-aminophenyl)ethoxy]phenyl}-2-ethoxypropanoic acid ethyl ester (0.89 g; 2.49 mmole) in dichloromethane (8.9 ml) at 0° C. After stirring at room temperature for 20 hours the reaction mixture was poured onto a mixture of hydrochloric acid and ice. Dichloromethane was added, the phases were separated and the organic phase was washed with water, dried (sodium sulfate), filtered and the solvent was evaporated in vacuo. Purification by chromatography on silica gel using heptane:ethyl acetate (3:2) as eluant gave 0.78 g (yield 72%) of 2-ethoxy-3-{4-[2-(4-methanesulfonylaminophenyl)ethoxy]phenyl}propanoic acid ethyl ester.
