Reaction Conditions

Reaction Steps

Synthesized from ethyl [5-methoxy-2-(6-methoxy-1,2,3,4-tetrahydronaphthalen-2-yl)phenyl]amine and 4-bromobenzoyl chloride according to an analogous synthetic method to Preparation Example 86, to a suspension of the resulting 4-bromo-N-ethyl-N-[5-methoxy-2-(6-methoxy-1,2,3,4-tetrahydronaphthalen-2-yl)phenyl]benzamide (299 mg) in 1,4-dioxane (10 ml) were sequentially added 1-(2-aminoethyl)piperidine (0.13 ml), sodium tert-butoxide (88 mg), (±)-2,2′-bis(diphenylphosphino)-1,1′-binaphthyl (23 mg) and tris(dibenzylideneacetone)dipalladium(0)chloroform adduct (13 mg), and the solution was stirred overnight at 100° C. The solution was let to cool, then the insoluble material was filtered through celite pad, and the solvent was evaporated in vacuo. The residue was purified by NH silica gel column chromatography (hexane-ethyl acetate-tetrahydrofuran system) to provide the title compound (253 mg).
