Hydrochloric Acid → Tetrahydrofurfuryl 2-(4,6-dimethoxypyrimidin-2-yl)oxybenzoate

Participants

Reaction Steps

0.55 Gram of 2-(4,6-dimethoxypyrimidin-2-yl)oxybenzoic acid, 0.21 g of tetrahydrofurfuryl alcohol and 0.85 g of 2,4,6-triisopropylbenzenesulfonyl chloride were dissolved in 5 ml of tetrahydrofuran. Subsequently, 0.45 g of 1-methylimidazole was added to the mixture. After stirring the resulting solution at room temperature for 1 hour in order to carry out the reaction, the reaction solution was poured into diluted hydrochloric acid, and extracted with ethyl acetate. The organic layer separated from the aqueous layer was washed with saturated sodium chloride solution and dried over anhydrous magnesium sulfate. The solvent was removed under reduced pressure, and the residue obtained was subjected to silica gel column chromatography (mfd. by Merck & Co., Inc., solvent: chloroform) to obtain 0.30 g of tetrahydrofurfuryl 2-(4,6-dimethoxypyrimidin-2-yl)oxybenzoate [present compound (III-g)].
