Reaction Steps
Combine citric acid (370 mg, 0.80 mmol) and ethanol (4 mL) and heat until the solid dissolves. Combine (E)-1-[4-(6-diethylaminohexoxy)phenyl]-1,2-diphenyl-2-chloro-ethylene (154 mg, 0.80 mmol) and warm ethanol (5 mL) and add with stirring to the citric acid solution prepared above. Filter while still warm and then cool in a freezer at -20° C. until crystals begin to form and then allow to stand at ambient temperature for 18 hours. Filter to give the title compound as a solid: mp; 84°-87° C.
