Reaction Steps

To a solution of 4-[3-(5-bromo-2-thienyl)-1H-pyrazol-4-yl]pyridine (1 eq, 8.8 mmol) in 50 mL N,N-dimethylformamide were added 1-bromo-2-methylpropane (1.5 eq, 13.2 mmol) and cesium carbonate (1.1 eq, 9.7 mmol). The reaction mixture was stirred overnight at room temperature and poured in 500 mL of water. The resulting precipitate was filtered and dried. The solid was then recristallised in a mixture diisopropylether:dichloromethane to afford 1.81 g of 4-[1-isobutyl-3-(5-bromo-2-thienyl)-1H-pyrazol-4-yl]pyridine (53% yield).
