Synthesis

111 g (416 mmol) of 6’-bromo-2’-fluorobiphenyl-2-ol are dissolved in 21 of SeccoSolv DMF (max 0.003% of H20) and cooled to 5°C. 20 g (449 mmol) of sodium hydride (60% suspension in paraffin oil) are added in portions tothis solution, and the mixture is stirred for a further 20 mm. after the addition is complete and then heated at 100°C for 45 mm. After cooling, 500 ml of ethanol are slowly added to the mixture, which is then evaporated to dryness in a rotary evaporator and purified by chromatography. Yield: 90 g (367 mmol), 88.5% of theory.
