1,2-Dibromoethane → Ethyl 4'-(2-bromoethoxy)-3'-(5,5,8,8-tetramethyl-5,6,7,8-tetrahydronaphth-2-yl)biphenyl-4-carboxylate

Participants

Reaction Steps

In a manner similar to that of Example 1a, by reaction of 6 g (14 mmol) of ethyl 4′-hydroxy-3′-(5,5,8,8-tetramethyl-5,6,7,8-tetrahydronaphth-2-yl)biphenyl-4-carboxylate with 4 ml (46.2 mmol) of 1,2-dibromoethane. 2.12 g of ethyl 4′-(2-bromoethoxy)-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=28%).
