Reaction Steps
In 20 ml of EtOH, 9.4 g (6.4×10−2 mole) of phthalimide and 4.2 g of KOH were stirred for 30 minutes, followed by addition of 100 ml of DMF (dimethylformamide) and 5.2 g (2.5×10−2 mole) of 6-chloro-3-pyridylmethyl chloride. The mixture was stirred at 60° C. for 1 hour. The EtOH and DMF were distilled off under reduced pressure and the residue was chromatographed on a silica gel column and eluted with CH2Cl2. The above procedure gave 6.7 g of the title compound as colorless needles.
