실험 절차

A mixture of 3-(4-bromobutyl)-2-methyl-1-thia-3-azaspiro[4.4]nonan-4-one (6.80 g), 1-(1-phenyl-1H-indol-3-yl) piperazine dihydrochloride (4.80 g), diisopropylethyl amine (8.16 g), K2CO3 (9.50 g), NaI (400 mg) and CH3CN (200 ml) was heated at 80° C. under nitrogen for 24 hours. The mixture was cooled and filtered, the inorganics were washed with dichloromethane, and the filtrate was concentrated under reduced pressure to a residue. The residue was diluted with 0.5N NaOH (150 ml) and the aqueous mixture extracted with ether (3×100 ml). The combined ether (Na2SO4) and concentrated in vacuo. The crude product was chromatographed on extracts were washed successively with H2O (150 ml) and brine (150 ml), dried silica gel, eluting with a gradient of 5-10% methanol in dichloromethane. The fractions containing the desired product (Rf =0.42, 10% methanol in dichloromethane) were concentrated to afford 4.84 g of a viscous liquid. The salt of this amine was precipitated from ether by the addition of ethereal HCl. A 4.74 g portion of the salt was recrystallized from ethanol yielding 2.15 g of solid, m.p. 214°-217° C.
