반응 단계

A suspension of 2-((2-chloro-5-cyano-3-vinylphenyl)amino)-4-(cyclopropylamino)imidazo[2,1-f][1,2,4]triazine-7-carbonitrile (210 mg, 0.557 mmol) in acetone (50 mL) was heated to give a cloudy solution. After cooling to RT, water (5 mL), osmium tertroxide (0.350 mL, 2.5 wt % in t-BuOH, 0.028 mmol) and sodium periodate (262 mg, 1.23 mmol) were added. This was stirred overnight. Additional water (20 mL) was added and the reaction was left stirring for 1 day. Most of the acetone was removed and the suspended solid was collected by filtration, washed with water, and air dried to leave 2-((2-chloro-5-cyano-3-formylphenyl)amino)-4-(cyclopropylamino)imidazo[2,1-f][1,2,4]triazine-7-carbonitrile (188 mg) as a light yellow solid.
