Procedimiento

To a mixture of N-(4-hydroxy-2,3,6-trimethylphenyl)formamide (660.4 g), potassium carbonate (1019 g) and dimethylformamide (3302 ml) was added a solution of 1-(3-chloro-2-methyl-1-propenyl)-4-methylbenzene (755 g) in toluene (675 ml), and the mixture was stirred at 50° C. for 14 hr. Water (5944 ml) was then added thereto and the mixture was stirred at 30° C. for 1 hr. The precipitated crystals were collected by filtration and washed with water and isopropylether to give the title compound (940 g, yield 74.5%).
