Participants

Reaction Steps

To a stirred solution of 5-methoxy-4-[3-(5-methyl-pyrazin-2-yl)-ureido]-2-trifluoromethyl -benzoic acid (37 mg, 0.1 mmol) in 1 mL NMP at room temperature in a capped reaction vial was added HBTU (42 mg, 0.11 mmol) and the suspension stirred for 15 minutes. 2-aminoethylpyridine (13 μL, 0.11 mmol) was added followed by DIEA (35 μL, 0.2 mmol) and the reaction was stirred overnight. NMP was then removed by bulb to bulb transfer under high vacuum at 70° C. and the residue triturated and filtered with EtOAc to give the desired amide as a tan solid (32 mg, 68%). 1H-NMR (400 MHz, d6-DMSO) δ8.90 (br s, 1H), 8.66 (d, 1H, 8.61 (s, 1H), 8.52 (t, 1H), 8.23 (s, 1H), 8.10 (br m, 1H), 7.61 (br d, 1H), 7.57 (br m, 1H), 7.07 (s, 1H), 4.00 (s, 3H), 3.62 (m, 2H), 3.11 (m, 2H), 2.42 (s, 3H) LRMS (esi, positive) m/e 475.1 (M+1)
