Procedure
3-Ethylphenol (24.4g) and 4-fluorobenzoyl chloride (34.9g) were reacted together as in Example 11 giving three main fractions: B (11.4g) 126°-129°C at 0.07 mmHg; C (7.9g), 129°-132°C at 0.06 mmHg; D (5.9g), 132°-150°C at 0.06 mmHg, all containing ~80% of the required isomer. B (4.0g) was separated by preparative thin layer chromatography to give the title compound (2.6g), m.p. 44°-48°C.
