Reaction Steps

A suspension of 4-(1H-indazol-3-yl)piperazine (1.6 g, 7.9 mmol), N-(2-bromoethyl)phthalimide (2.1 g, 7.9 mmol), and sodium bicarbonate (0.7 g, 8.3 mmol in acetonitrile (160 ml) was warmed to reflux for 24 hours. Upon cooling to room temperature, the reaction mixture was filtered through a pad of celite and the solids; were washed with DCM. The combined filtrates were concentrated to give the N-[2-[4-(1H-indazol-3-yl)-1-piperazinyl]ethyl]phthalimide which was used without further, purification.
