Procedure
In a manner similar to Example 1(j), by reacting 0.3 ml of concentrated sulphuric acid in 7 ml of methanol with 700 mg (1.41 mmol) of 9-{3-[2-(3,5-bis-ethoxymethoxyphenyl)vinyl]phenyl}-3-ethylnon-8-en-3-ol in 7 ml of methanol and 7 ml of THF, after purification on a silica column (ethyl acetate 40-heptane 60), beige crystals (m=477 mg; Y=77%) are obtained. m.p.=98-102° C.
Workup
- customafter purification on a silica column (ethyl acetate 40-heptane 60), beige crystals (m=477 mg; Y=77%)
