Reaction Steps
1-{3-tert-Butyl-5-[2-(tetrahydropyran-2-yloxy)ethoxy]phenyl}ethanone (O2.061; 3.9 g) was dissolved in methanol/THF (60 ml/60 ml) and admixed while stirring with phenyltrimethylammonium tribromide (5.03 g). After stirring at RT for 3 h, the reaction mixture was added to 20% citric acid and stirred for 1 h. After adding EA, the EA phase was removed, dried and concentrated. The residue was purified using silica gel (80 g cartridge, n-heptane/EA gradient of 0-50% within 60 min). 2.56 g of the title compound were obtained.
