Методика

Methyl 2-chloro-3-{4-[2-(4-hydroxyphenoxy)ethyl]phenyl}propanoate (334 mg, 1.0 mmol) and triethylamine (303 mg, 3.0 mmol) was dissolved in 20 ml dichlormethane and cooled to −20° C. under nitrogen atmosphere. Methanesulfonyl chloride (114 mg, 1.0 mmol) was added dropwise. The mixture was allowed to reach room temperature. After 2 hours dichlormethane was added, the mixture was washed (water, brine), dried (Na2SO4) and evaporated under reduced pressure to yield 394 mg pure product (yield 96%).
