Reaction Steps

1-(2-chlorophenyl)-trans-1-propene (2.5 g, Preparation Example 1) was dissolved in 50 mL of the mixture of t-BuOH/H2O (1:1(V/V)). At 0° C., AD-mix-α (Aldrich, U.S.A.) (23.5 g) and methane sulfone amide (CH3SO2NH2, 1.27 g, 0.013 mol) were added thereto and stirred for overnight. When the reaction was completed, the obtained product was washed with an aqueous solution of sodium sulfite (Na2SO3) and ethylacetate (EA). Then, the organic layer was dehydrated with anhydrous magnesium sulfate (MgSO4), filtrated, and concented under reduced pressure. The concentrated residue was purified by a silica gel column chromatography to produce the title compound (2.96 g, yield 90%).
