Diethyl Ether → HCID 67050265, compound

Participants

Reaction Steps

To a solution of 2-(4-t-butylphenyl)-3-methoxymethyloxy-4-formylthiophene (3.0 g, 10 mmol) in THF (2.5 mL), 2.0 M ethyl ether solution (6.0 mL, 12 mmol) of isopropylmagnesium bromide was added dropwise under cooling with ice, followed by stirring for 2.5 hours under cooling with ice. A saturated ammonium chloride aqueous solution was added to the reaction solution, and then extraction was carried out with ethyl acetate, and the organic layer was washed with a saturated sodium chloride solution and then dried over anhydrous sodium sulfate. The obtained organic layer was concentrated, and then purification was carried out with a silica gel column chromatography (n-hexane/ethyl acetate=3/1) to obtain the desired product as a pale yellow oil (1.18 g, yield 34%).
