YieldReaction ConditionsOperation in experiment
82% With bromine; In chloroform; at 60℃; for 1h; Synthesis of methyl 5-bromo-4-fluorothiophene-2-carboxylateBr2 (2.29 g, 14.4 mmol, 0.740 ml) was added to a mixture of <strong>[32431-75-7]methyl 4-fluorothiophene-2-carboxylate</strong>(0.230 g, 1.43 mmol) in CHCI3 (5 mL) and the mixture was warmed up to 60 00 and stirred for 1 h. Thesolution was cooled to RT and poured in an aqueous solution of Na2S2O3 (10%, 10 mL) and stirred for 30 mm. The phases were separated and the aqueous layer extracted with DCM (3x 10 mL). The collected organic layer was washed with brine (20 mL), dried over Na2SO4 and evaporated in vacuo to leave a yellow solid (0.800 g). The solid was sublimated in the kugelrohr at 150 C under vacuum (50 torr) to yield methyl 5-bromo-4-fluorothiophene-2-carboxylate 0.280 g 1.17 mmol, 82%).
