Procedure
In a manner similar to that of Example 6a, by reacting 2 g (6 mmol) of ethyl 3′-bromo-4′-hydroxybiphenyl-4-carboxylate with 320 mg (8 mmol) of 60% sodium hydride and 0.7 mL (7 mmol) 2-bromoethan-1-ol acetate, 2.2 g of ethyl 4′-(2-acetoxyethoxy)-3′-bromobiphenyl-4-carboxylate are obtained (yield=95%) in the form of a colorless oil.
Workup
- customare obtained (yield=95%) in the form of a colorless oil
