実験手順

10 g (52 mmol) of 4-bromothiophene-2-carbaldehyde are dissolved in 200 mL of ethyl ether and 20 mL of THF. 26.6 mL (78 mmol) of 3.0M ethylmagnesium bromide are added slowly. After 2 hours at room temperature, the reaction medium is poured into saturated ammonium chloride solution. After extraction, a yellow oil is obtained (m=11.5 g, Y=99%).
