참여 물질

반응 단계

To a cold mixture (0° C.) of 209 g (200 mmol) of chromium trioxide, 100 ml (1.06 mol) of acetic anhydride and 200 ml (3.5 mol) of acetic acid was added a solution of 10 g (41.8 mmol) of 6-bromo-1,2,3,4-tetrahydro-1,1-dimethylnaphthalene (Compound F) in 125 ml of benzene. The reaction mixture was stirred for 1 hour, quenched with ice cold water and extracted with Et2O (3×100 ml). The organic layer was dried over MgSO4, concentrated in vacuo, and purified by column chromatography (silica, 10% EtOAc-hexane) to give the title compound as a white solid.
