Abstract

Przedmiotem zgłoszenia jest sposób otrzymywania 7-metoksy-1,2,3-tris(4-metoksyfenylo)-1,2,3,4-tetrahydronaftalenu o wzorze 1. Sposób ten polega na tym, że (E)-4,4'-dimetoksystilben rozpuszcza się w chlorku metylenu, dodaje się jod 1-1 mol/mol w stosunku do stilbenu i miesza przez co najmniej 20 godzin w temperaturze 20 - 30°C, następnie do mieszaniny reakcyjnej dodaje się wodę i poddaje kilkakrotnie ekstrakcji a połączone fazy organiczne przemywa się wodnym roztworem pirosiarczynu sodu, a następnie wodą po czym warstwę organiczną suszy się bezwodnym MgSO4 i zatęża.The subject of the application is a method for obtaining 7-methoxy-1,2,3-tris (4-methoxyphenyl) -1,2,3,4-tetrahydronaphthalene of formula 1. This method consists in the fact that (E) -4,4 ' -dimethoxystilbene is dissolved in methylene chloride, iodine 1-1 mol / mol is added to stilbene and stirred for at least 20 hours at 20-30 ° C, then water is added to the reaction mixture and extracted several times and the combined phases the organic was washed with aqueous sodium metabisulfite and then with water, and the organic layer was dried over anhydrous MgSO 4 and concentrated.
