Procedure

Acetic anhydride (4.8 μL, 0.5.1 μmol) was added to a mixture solution of 3-(3-(4-(2-(dimethylamino)ethoxy)phenyl)-1-(pyridin-4-yl)-1H-indol-6-yl)benzenamine (2.2 mg, 4.9 μmol) in pyridine (0.4 mL) at room temperature. After stirring for 15 hours at room temperature, the reaction solution was added to saturated sodium bicarbonate aqueous solution and then extracted with ethyl acetate. The collected organic layer was washed with brine and concentrated under reduced pressure by drying with anhydrous magnesium sulfate. The residue was purified by chromatography (preparative TLC, DCM:MeOH=10:1). The target compound (1.5 mg) was obtained as white solid.
