Water → 1-(2-Nitro-ethyl)-4-phenoxy-benzene

Participants

Reaction Steps

To a solution of 1-((E)-2-nitro-vinyl)-4-phenoxy-benzene (1.40 g, 2.90 mmol, purity: 50%) described in Manufacturing Example 17-1-2 in methanol (15 mL) was added sodium borohydride (274 mg, 7.25 mmol) at room temperature while cooling appropriately under nitrogen atmosphere, which was stirred for 10 minutes at room temperature. Water was then added dropwise at room temperature while cooling appropriately. The reaction mixture was extracted with ethyl acetate. The organic layer was washed with water and saturated aqueous sodium chloride, and dried over anhydrous magnesium sulfate, and the solvent was evaporated under a reduced pressure. The residue was purified by silica gel column chromatography (ethyl acetate:heptane=1:5) to obtain the title compound (199 mg, 28%).
