Procedure

2-(1-Chloro-2-methyl-2-nitropropyl)naphthalene (200 mg) obtained in Step 4 was dissolved in methanol (5 ml) and ethyl acetate (5 ml) and to the solution was added 10% palladium carbon (20 mg). A hydrogenation reaction was performed at pressure of 3 atm for 2 hr. After filtration of the reaction mixture using Celite, the title compound (139 mg) was obtained by purification using silica gel column chromatography (n-hexane:ethyl acetate=95:5).
