Reaction Steps

A mixture of 4-(4-cyclopropyl-1H-imidazol-1-yl)-N-(5-(hydrazinecarbonyl)thiophen-3-yl)picolinamide (130 mg, 0.35 mmol) and toluene (2 mL) were added to a sealable vial. N,N-dimethylformamide/N,N-dimethylacetamide complex (120 μL, 0.88 mmol) was added and the reaction was stirred for 5 minutes. (S)-3-methylbutan-2-amine (170 μL, 1.4 mmol), and acetic acid (20 μL, 0.35 mmol) were added, and the reaction was heated in a microwave reactor at 150° C. for 30 minutes. The reaction was concentrated and purified by RP-HPLC to provide 65 mg (42%) of (S)-4-(4-cyclopropyl-1H-imidazol-1-yl)-N-(5-(4-(3-methylbutan-2-yl)-4H-1,2,4-triazol-3-yl)thiophen-3-yl)picolinamide as a white solid.
