Sodium hydride → HCID 14986330, compound

Participants

Reaction Steps

To a suspension of 0.14 g (3.5 mmol, 60% on oil) of sodium hydride in 10 mL of anhydrous dimethylformamide stirred at room temperature was added 0.88 g (3.1 mmol) of 2,4-dihydroxy-3-propylbenzoic acid phenylmethyl ester. The reaction mixture was stirred for 2 hours and then 1.09 g (3.1 mmol) of 1-(6-bromohexyl)-2,3-bis(acetyloxy)benzene in 10 mL of dimethylformamide was added dropwise. Stirring at 50° was continued for 16 hours and then the solvent was removed on the oil pump. The crude product was purified by HPLC using 25% ethyl acetate-hexane to give 0.55 g (28% yield) of 4-[6-[2,3-bis(acetyloxy)phenyl]hexyloxy]-2-hydroxy-3-propylbenzoic acid phenylmethyl ester as an oil.
