Procedure
4-(3,4,5-trimethoxy-benzyl)-piperazine-2-carboxylic acid ethyl ester (2.0 g, 5.91 mmol) was dissolved in dry benzene (30 ml) followed by addition of triehylamine (0.65 g, 6.5 mmol) and resulting solution stirred for 1 hr. 1-[6,6-bis-(4-fluoro-phenyl)-hexyl bromide(2.08 g, 5.91 mmol) in dry benzene (30 ml) was added dropwise. The resulting mixture was stirred under nitrogen at room temperature overnight. The mixture was washed twice with water (30 ml) and dried over MgSO4 and evaporated. The crude product was purified by column chromatography using hexane:ethyl acetate (3:1) to give the desired product in 56% yield
