Reaction Steps

3-Bromo-6,6-dimethyl-8-[1-(2,2,2-trifluoro-acetyl)-piperidin-4-yloxy]-5,6-dihydro-benzo[b]carbazol-11-one (Compound T6-1, 28.0 mg, 52.3 μmol) was dissolved in THF (1.00 mL) and methanol (0.50 mL), added with aqueous solution of potassium hydroxide (1.00 mL, 20 wt %), and stirred at room temperature for 1 hr. The reaction solution was added to water, and extracted with mixture solution of chloroform and methanol, and dried over sodium sulfate. Then, after filtering and concentration under reduced pressure, 3-bromo-6,6-dimethyl-8-(piperidin-4-yloxy)-5,6-dihydro-benzo[b]carbazol-11-one was obtained as a crude product.
