Procedure

To an ice-cold solution of 6-(3-ethylureido)-4-(phenylamino)nicotinic acid (50 mg, 0.16 mmol, 1.0 eq) in DMF (2.0 mL) was added HBTU (91 mg, 0.24 mmol, 1.50 eq) followed by DIPEA (62 mg, 0.48 mmol, 3.0 eq) and finally 2-chloroaniline (24 mg, 0.19 mmol, 1.20 eq). The resulting reaction mixture was stirred overnight at room temperature. The reaction mass was then poured onto ice-cold water followed by extraction with EtOAc (3×20 mL). The organics were combined, washed with brine, dried over anhydrous Na2SO4, filtered and concentrated under reduced pressure. The residue was purified over silica gel (60-120 M, 1-2.5% MeOH-DCM) to obtain Compound 9 (10 mg, 15%). NMR (300 MHz, DMSO-d6): δ 10.17 (br s, 1H), 10.08 (br s, 1H), 9.12 (s, 1H), 8.67 (s, 1H), 7.87 (m, 1H), 7.56 (m, 1H), 7.24-7.40 (m, 8H), 7.15 (m, 1H), 3.14 (m, 2H), 1.06 (t, J=7.20 Hz, 3H). [M+H]+ m/z=410.15.
