반응 단계

Cyclopropylmagnesium bromide (150 mL, 0.5M in tetrahydrofuran) was slowly added to a solution of 1-bromonaphthalene (10 g, 50 mmol) and [1,3-bis(diphenylphosphino)propane]dichloro nickel (II) in tetrahydrofuran (10 mL) stirred at 0° C., and the reaction mixture stirred at room temperature for 16 hours. The solvent was removed under reduced pressure and ethyl acetate and aqueous ammonium chloride were added. After extraction, the organic layer was dried over sodium sulfate, filtered and concentrated under reduced pressure. The residue was purified by silica gel chromatography to yield 1-cyclopropylnaphthalene (6.4 g, 76%).
