Reaction Steps

To a solution containing 7-chloro-5-methylpyrrolo[1,2-b]cinnolin-10(5H)-one (3.0 g) and a catalytic amount of dibenzoyl peroxide in 50 ml of THF was added portionwise N-chlorosuccinimide (1.74 g) over 15 min. The flask was covered with aluminum foil and the solution stirred at room temperature for 24 hrs. The solution was then concentrated and the residue purified by HPLC (silica, dichloromethane) to give 2.43 g of a yellow powder.
