Reaction Steps

(1H-Indol-2-yl)-(4-methyl-piperazin-1-yl)-methanone (Example 4, 0.222 g) in acetic acid (1 mL) at ambient temperature was treated with bromine (0.05 mL) and stirred for 7 h. The reaction mixture was poured into water and adjusted to basic pH by addition of 1 M sodium hydroxide. The mixture was extracted with dichloromethane. The organic extracts were combined, dried over sodium sulfate, filtered, and concentrated to give crude product. Purification via silica gel chromatography, eluting with 1-8% methanol/dichloromethane, afforded the title compound (0.154 g).
