Procedure

1-(3-tert-Butyl-5-hydroxy-4-methoxyphenyl)ethanone (03.070; 2.00 g) and 1-bromo-2-methoxyethane (1.5 g) were dissolved in DMF (20 ml), and sodium hydride (259 mg) was added. After stirring at RT for 3 h, the mixture was left to stand overnight. Then the DMF was drawn off and the residue was taken up in EA. The EA phase was washed with water, dried, filtered and concentrated. The residue was purified using silica gel (80 g cartridge, n-heptane/EA 0-40% within 60 min). 1.17 g of the title compound were obtained.
