Participants

Reaction Steps

Under protective gas conditions, at about −78° C., 1 ml of a 1-molar solution of LiAlH4 in tetrahydrofuran was added dropwise to a solution of 0.37 g of 2,5-dichloro-6,6′-dimethyl-2′, 3′, 4′-trimethoxybenzophenone in 20 ml of anhydrous tetrahydrofuran, and the mixture was stirred for about 1 hour. At 20-25° C., sat. NaHCO3 solution was added to the reaction solution, the solution was extracted with ethyl acetate and the organic phase was washed with water and sat. NaCl solution and dried, and the solvent was then distilled off. The residue gave, after purification by column chromatography (mobile phase: ethyl acetate/cyclohexane 1:9), 150 mg of the title compound as a yellow viscous oil.
