Procedure

Methyl 3-[2-[(1R)-1-(((2R)-oxiranyl)methoxy)ethyl]phenyl]propionate (286 mg) obtained in Step 3 was dissolved in acetonitrile (10 ml), [2-methyl-1-(naphthalen-2-yl)propan-2-yl]amine (218 mg) and lithium perchlorate (157 mg) were successively added, and the mixture was heated under reflux overnight. The reaction mixture was concentrated under reduced pressure. The obtained residue was purified by silica gel column chromatography (chloroform:methanol=10:1) to give the title compound (539 mg).
