실험 절차

A mixture of 1-indanylacetic acid (CIX, EXAMPLE 66, 7.4 g, 42 mmol) and triethylamine (29.3 ml, 210 mmol), and 1-(4-methoxyphenyl)piperazine dihydrochloride (LXV, 13.3 g, 50.4 mmol) in methylene chloride (420 ml) is stirred at 20-25° under a nitrogen atmosphere. Diethylcyanophosphonate (12.7 ml, 84 mmol) is added over a period of 10 min at 20-25°. After the stirring for 3 hr, the reaction is quenched with sodium hydroxide (20%) and extracted with methylene chloride (2×500 ml). The organic phase is washed with saline, dried (magnesium sulfate), filtered and concentrated under reduced pressure. The crude product is purified by crystallization from ethyl acetate/methanol. The mother liquor is purified by liquid chromatography on silica gel 60 (230-400 mesh, 400 g), eluting with hexane/ethyl acetate (1/2). The appropriate fractions homogeneous by TLC are combined and concentrated under reduced pressure to give a solid. Both solids are combined to give the title compound, mp=111-112°; NMR (CDCl3, TMS) 7.26-6.83, 3.77 and 3.85-1.54 δ.
