Procedure
To a solution of 10.0 g (30.5 mmol) of 2-bromo-1-(4-hydroxy-3,5-di-tert-butylphenyl)-ethanone and the 8.8 g (30.5 mmol) of 5-chloro-2-(2,4-di-chloro-phenoxy)-phenol in 50 ml of tetrahydrofuran, 6.3 g (45.7 mmol) of potassium carbonate is added and the mixture is stirred for 4 days at room temperature. After addition of water and adjusting the pH to 5-6 by adding 32% HCl, the mixture is extracted with ethyl acetate. The combined extracts are washed with water, dried and evaporated. Crystallization of the crude product from methanol gives 15.4 g of compound 104, m.p. 111-114° C.
