실험 절차

30 g (157 mmol) of 4-bromo-2-thiophenecarboxaldehyde are dissolved in 200 mL of anhydrous THF. 104 mL (312 mmol) of 3.0 M ethylmagnesium bromide are added slowly and the medium is stirred for 2 hours at room temperature. After the usual treatment, an orange-coloured oil is obtained (m=33.5 g; Y=96%).
