Procedure
10 g (43.8 mmol) of 4′-hydroxybiphenyl-4-carboxylic acid methyl ester, 100 ml of THF and 150 ml of DMF are introduced in order and under a nitrogen stream into a 500 ml three-necked flask. 1.93 g (48.2 mmol) of NaH at 60% in oil are added in small portions and the mixture is stirred at room temperature for 15 hours. 5.75 ml of 1-chloromethoxy-2-methoxyethane are added dropwise, and the mixture is stirred at room temperature for 30 minutes. The reaction medium is poured over a 1N HCl solution and extracted with ethyl acetate. The organic phase is washed with water and dried over magnesium sulphate. After filtration and evaporation 12 g of 4′-(2-methoxyethoxymethoxy)biphenyl-4-carboxylic acid methyl ester are obtained in the form of a beige powder after filtration and evaporation (yield=87%).
