Procedure

A solution of 7-bromo-3,4-dihydro-2H-naphthalen-1-one (600 mg), morpholine (1.16 g), tripotassium phosphate (850 mg), tris(dibenzylideneacetone)dipalladium (0) (24.4 mg) and 2-(di-tert-butylphosphino)biphenyl (15.9 mg) in toluene (5.0 mL) was stirred in a nitrogen atmosphere at 100° C. overnight. Water and ethyl acetate were added to the reaction solution and the organic layer was partitioned. The organic layer was washed with brine, and then dried over anhydrous magnesium sulfate and concentrated under reduced pressure. The resulting residue was purified by silica gel chromatography (elution solvent: heptane-ethyl acetate system) to obtain 360 mg of the title compound. The physical properties of the compound are as follows.
