Reaction Steps

Placed 4-(2-aminopyridin-3-yloxy)benzonitrile (13.95 g, 66.05 mmol) in acetic acid (50 mL) and cooled to 0° C. Slowly added bromine (4.229 mL, 82.56 mmol) and stirred for an hour. The reaction mixture was poured onto saturated sodium bisulfite and ice. Extracted with dichloromethane three times, washed with 2N NaOH, water, brine, dried, and concentrated. Purified by MPLC eluting with 3:2 hexane:ethyl acetate to afford the title compound (12.7 g, 66.28% yield) as a light yellow solid.
