Procedure

A stirred mixture of 2-[4-(6-fluoro-1,2-benzisoxazol-3-yl)-1-piperidinyl]ethylamine (2.63 g, 0.01 mole) and 4-chlorophthalic anhydride (1.82 g, 0.01 mole) in dichloromethane (100 ml) is stirred at room temperature for 3 hours. The solvent is removed under reduced pressure and the residual material is purified by flash chromatography. The product was purified further by recrystallization to give N-[2-[4-(6-fluoro-1,2-benzisoxazol-3-yl)-1-piperidinyl]ethyl]-4-chlorophthalimide.
