Conditions: temp:0.00; pressure:0.00; stir:

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: In a manner similar to that of Example 17a, by reaction of 600 mg (1.4 mmol) of ethyl 4′-hydroxy-3′-(5,5,8,8-tetramethyl-5,6,7,8-tetrahydronaphth-2-yl)biphenyl-4-carboxylate with 475 mg (1.68 mmol) of N-(4-bromobutoxy)phthalimide and 230 mg (1.66 mmol) of potassium carbonate in 50 ml of acetone. 790 mg of ethyl 4′-[4-(1,3-dioxo-1,3-dihydroisoindol-2-yl)butoxy]-3′-(5,5,8,8-tetramethyl-5,6,7,8-tetrahydronaphth-2-yl)biphenyl-4-carboxylate are obtained in the form of a white solid (yield=90%).
