  4-(6-Acryloyloxyhexyloxy)-benzoesure (4-cyanophenylester) can be used as an intermediate in organic synthesis, mainly used in laboratory research and development and in the process of chemical and pharmaceutical synthesis.

• Synthesis

  
  The target monomer was prepared by firstly converting the acid into the corresponding acid chloride, then condensing this withp-cyanophenol. The acid (17.32 g, 0.059 mol) was stirred with thionyl chloride (35.7 g, 0.3 mol) in the presence of DMF (2 drops) and 2,6-di-tert-butyl-4-methyl phenol (4.4 g, 0.02 mol). After ca. 25 min, by which time solution was achieved, the excess thionyl chloride was removed by rotary evaporation and high vacuum (1-2 h). The acid chloride residue was dis- solved in anhydrous chloroform (30 mL), then added slowly dropwise into a stirred solution of p-cyanophenol (7.03 g, 0.059 mol) and triethylamine (6.07 g, 0.06 mol) in chloroform (20 mL) at 0??C. After the addition the mixture was stirred at room temperature for 24 h and then chloroform (200 mL) added. This solution was washed with water (50 mL) followed by 2 N sodium hydroxide solution (3 x 50 mL) and water (2 x 50 mL). The organic layer was dried (MgSO,), evaporated, then subjected to flash chromatography, using dichloro- methane as both the solvent and the eluant. The monomer was finally recrystallized from isopropanol and shown to be pure by tlc. Yield: 16 g, 69%.
