Procedure

A solution of 5-oxo-5,6,7,8-tetrahydronaphthalen-2-yl trifluoromethanesulfonate (3.40 g), morpholine (5.18 g), tripotassium phosphate (3.79 g), tris(dibenzylideneacetone) dipalladium (0) (109 mg) and 2-(di-tert-butylphosphino)biphenyl (71 mg) in 1,2-dimethoxyethane (24 mL) was stirred in a nitrogen atmosphere at 80° C. for one and a half hours. The reaction solution was returned to room temperature, and 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 2.56 g of the title compound. Properties data of the compound are as follows.
