Reaction Steps

3-[(4-iodo-2-methylphenyl)amino]isonicotinic acid 2c (60 mg, 0.17 mmol) was dissolved in 6 ml dry DMF followed by the addition of DIPEA (0.20 mmol, 37 μl), ByBOP (0.20 mmol, 107 mg) and O-ethylhydroxylamine hydrochloride (0.34 mmol, 34 mg). The mixture was stirred for 4 h and the volatiles were removed in vacuo. The crude material was purified by preparative reversed phase HPLC to give 36 mg (91 μmol; 53% yield) of pure desired product.
