実験手順

In a similar manner to that described in Reference example 25, a reaction was carried out using ethyl 3-(4-hydroxyphenyl)-2-(4-methylphenoxy)propionate (300 mg), which is the-product of Reference example 35(c), t-butyl 2-methanesulfonyloxy-ethylcarbamate (598 mg) and potassium carbonate (691 mg) and the reaction mixture was treated to afford the title compound (261 mg) as a colorless oil.
