Reaction Steps

To a solution of 2-chloro-4-[1-sec-butyl-3-(5-chloro-2-thienyl)-1H-pyrazol-4-yl]pyridine (0.28 mmol) in 1 mL of N,N-dimethylformamide was added zinc cyanide (0.14 mmol) and tetrakistriphenylphosphine palladium (O) (0.057 mmol). The resulting mixture was stirred in the microwave for 10 min at 120° C. After cooling to room temperature, the mixture was filtered and purified by preparative HPLC (column: Waters Sunfire C18, eluent:water/methanol/0.1% formic acid) to afford 56.7 mg of 2-cyano-4-[1-sec-butyl-3-(5-chloro-2-thienyl)-1H-pyrazol-4-yl]pyridine (55% yield).
