Yield:84807-09-0 90.8%

Reaction Conditions:

with potassium carbonate in isopropyl alcohol at 90; for 48 h;

Steps:

1.1 Step 1) Synthesis of 4-(piperazin-1-yl)-1H-indole

4-aminoindole (2g, 15.2mmol), bis(2-chloroethyl)amine hydrochloride (3.2g, 18.2mmol) and potassium carbonate (4.2g, 30.4mmol) was added to isopropanol (30 mL) after the reaction solution was reacted at 90 °C for 48 hours, and thereto was added dichloromethane (50mL) and methanol (50mL). The reaction mixture was filtered and the filtrate under reduced pressure to spin dry, the residue was purified by silica gel column chromatography (dichloromethane/methanol (v/v)= 10/1) by to give the title compound as a brown solid (2.78g, 90.8%).
