Dimethylformamide → HCID 21470422, compound

Participants

Reaction Steps

The above-prepared 6.20 g (19.1 mM) of 10-undecenyl p-toluenesulfonate, 4.62 g (19.1 mM) of ethyl p-hydroxybiphenylcarboxylate and 6 ml of dimethylformamide (DMF) were mixed and sufficiently stirred. To the mixture, 0.77 g (19.3 mM) of 60% -sodium hydride was added, followed by heat-refluxing for 7 hours. After the reaction, the reaction mixture was subjected to distilling-off of DMF and addition of water, followed by extraction with ether to obtain an extract. The extract was dried with anhydrous sodium sulfate, followed by distilling-off of ether and purification by column chromatography (eluent: methylene chloride) to obtain 6.46 g (16.4 mM) of ethyl p-(10-undecenyl)oxybiphenylcarboxylate (Yield: 86%).
