Reaction Steps

A mixture of 6-fluoro-3-(4-piperidinyl)-1,2-benzisoxazole (5.15 g, 23.4 mmol), K2CO3 (4.2 g, 30.4 mmol) and 2-bromoethyl phthalimide (7.13 g, 28 mmol) in acetonitrile (250 ml) was heated at reflux for 3.5 hours. The solids and solvent were removed. The residue was purified by flash chromatography (SiO2, 110 g, eluted with 2-4% CH3OH:DCM). The product thus obtained weighed 7.8 g (84%). Part of the material was recrystallized to give 2.35 g of off white crystals, m.p.=148°-149° C.
