Reaction Steps

To a solution of N-(isoxazol-3-yl)-N-(4-methoxybenzyl)-2-oxo-1-(2,3′,5′-trifluoro-5-hydroxy-[1,1′-biphenyl]-4-yl)-1,2-dihydroquinoline-6-sulfonamide (0.066 g, 0.104 mmol) in DMF (0.208 ml) at room temperature was added potassium carbonate (0.016 g, 0.115 mmol) followed by 2-bromopropanenitrile (0.014 ml, 0.156 mmol). The reaction mixture was stirred 16 hr. The resulting mixture was transferred to a sep.funnel containing water and the aqueous layer was washed 3× with DCM. The organic layers were combined, dried with MgSO4, filtered and concentrated to an oil. The crude material was taken onward to the next step without further purification, assuming quantitative yield. m/z (ESI) 687.1 (M+H)+.
