A mixture of methyl (2E)-3-(2-{(1R)-1-[(2R)-oxiran-2-yl methoxy]ethyl}phenyl)prop-2-enoate (342 mg, 1.30 mmol) described in WO 2004/106280, 1-(2,3-dihydro-1H-inden-2-yl)-2-methylpropan-2-amine (234 mg, 1.24 mmol) described in WO 01/53254, and lithium perchlorate (79 mg, 0.74 mmol) in toluene (12 mL) was stirred at room temperature for 16 hours. Water (10 mL) was added to the reaction solution, which was then extracted with ethyl acetate (10 mL×3). After that, the organic layers were combined, washed with saturated brine, and washed with anhydrous magnesium sulfate. The solvent was distilled off under reduced pressure. The residue was purified by silica gel column chromatography (ethyl acetate) to give the title compound as a colorless oily substance (206 mg, yield 37%).
