Triethylamine → 4-(6-Methacryloxyhexyloxy)-4'-nitrobiphenyl

Participants

Reaction Conditions

Reaction Steps

77 g 4-(6-hydroxyhexyloxy)-4'-nitrobiphenyl (see Example 4) is dissolved in 1500 ml absolute dioxane, and the solution is then heated to 45° C. Subsequently, 26.8 g triethylamine and 27.2 g methacrylic acid chloride, dissolved in the same volume of dioxane, are dripped in, then the reaction mixture is stirred for 24 h. Subsequently, the solvent is removed in a vacuum and the reaction mixture is suspended in water; the solid is filtered off, washed with water, dried and recrystallized from ethanol (melting point: 57° C.); yield: 80%.
