Reaction Steps

A solution of 4-fluorobenzoic acid (2.57 g, 18.3 mmol), quinolin-3-ylamine (2.5 g, 17.4 mmol), O-benzotriazol-1-benzotriazol-1-yl-N,N,N′,N′-tetramethyluronium hexafluorophospate (HBTU) (7.3 g, 19.3 mmol) and N,N-diisopropylethylamine (6.4 mL, 36.7 mmol) in acetonitrile (75 mL) was stirred at ambient temperature for ten minutes, then heated at reflux for 20 hours. The solution was cooled to 0° C., and the product crystallized. The product was collected by filtration and washed with acetonitrile, to give a colorless solid, 3.86 g (79%). MS: m/z 267 (MH+). 1H NMR(DMSO-d6): δ 7.39-7.46 (m, 2 H), 7.58-7.71 (m, 2 H), 7.97-8.01 (m, 2 H), 8.11-8.16 (m, 2 H), 8.85 (d, 1 H), 9.15 (d, 1 H) and 10.73 (s, 1 H).
