Reaction Conditions

Reaction Steps

To 2.01 g of the thus obtained 4-methoxymethyloxyphenyl 3-pyridyl ketone which has been dissolved in 35 ml of methylene chloride and cooled down to 0° C. was added dropwise 2.01 g of titanium tetrachloride dissolved in 35 ml of methylene chloride. After 2 hours of stirring at room temperature, the resulting reaction mixture was neutralized with saturated sodium hydrogencarbonate solution and mixed with 200 ml of ethyl acetate to separate the organic layer and to extract the water layer with ethyl acetate. Thereafter, the organic phases were combined, washed with saturated sodium chloride aqueous solution and dried using anhydrous magnesium sulfate, followed by the removal of solvents by distillation under a reduced pressure to obtain 1.32 g of 4-hydroxyphenyl 3-pyridyl ketone.
