Reaction Steps
3-(4-tert-Butyl-benzenesulfonylamino)-5-chloro-pyridine-2-carboxylic acid (75 mg, 0.20 mmol), (2-fluoro-phenyl)-methyl-amine (23 mg, 0.61 mmol), HATU (193 mg, 0.51 mmol), TEA (114 μL, 0.81 mmol) and 0.5 mL NMP were combined in a 4 mL vial and stirred overnight at 60° C. HPLC purification (10 to 95% gradient of MeCN-water) provided 3-(4-tert-butyl-benzenesulfonylamino)-5-chloro-pyridine-2-carboxylic acid (2-fluoro-phenyl)-methyl-amide: 1H NMR (400 MHz, CDCl3) 9.98 (s, 1H), 8.01 (s, 1H), 7.82 (d, 2H), 7.63 (s, 1H), 7.51 (d, 2H), 7.13 (m, 1H), 6.92 (t, 1H), 6.84 (t, 1H), 6.37 (m, 1H), 3.38 (t, 3H), 1.26 (s, 9H); MS m/z 476.1.
