To a solution of methyl 1-(5-bromopyridin-3-yl)cyclopropanecarboxylate (1 g, 3.9 mmol) in THF (40 mL) was added 90% KOTMS (0.557 g, 3.9 mmol), and the mixture was stirred at room temperature overnight. The mixture was filtered and washed with THF to give potassium 1-(5-bromopyridin-3-yl)cyclopropanecarboxylate. 1H NMR (400 MHz, DMSO-d6) δ ppm 0.63-0.69 (m, 2H), 1.09-1.15 (m, 2H), 7.79-7.80 (m, 1H), 8.34-8.37 (m, 2H).
