Methyl Isocyanate → 2-(3-(2-fluoro-4-iodophenylamino)isonicotinoyl)-N-methylhydrazinecarboxamide

Participants

Reaction Steps

To a suspension of 3-[(2-fluoro-4-iodophenyl)amino]isonicotinohydrazide (200 mg; 0.54 mmol) in methanol (10 mL) was added (methylimino)(oxo)methane (61 mg; 1.07 mmol) (methyl Isocyanate). After few minutes the reaction mixture became homogeneous, and then an yellow colored solid, 2-{3-[(2-fluoro-4-iodophenyl)amino]isonicotinoyl}-N-methylhydrazinecarboxamide (50 mg) was separated out. The filtrate upon concentration gave 158 mg which was also pure. (208 mg, 90%) MS m/z: 429 M+1
