Reaction Steps

H2SO4 (454 mg) was added cautiously to a suspension of 4-[2-(4-chloro-phenylamino)-1-methyl-1H-benzoimidazol-5-yloxy]-pyridine-2-carbonitrile (60.0 mg) in ethylenediamine (0.50 mL). The system was shaken at room temperature for 72 hrs, then poured onto ice/NaHCO3. The solid product was collected, washed (H2O) air-dried 59.8 mg. M/z=419 (M+1).
