Reaction Steps

A mixture of phenyl-piperazin-1-yl-acetic acid methyl ester (80 mg, 0.4 mmol), 4-bromo-N-(1-ethyl-propyl)-3-fluoro-benzamide (prepared as described in Example 113, Step A; 150 mg, 0.5 mmol), Pd2(dba)3 (6 mg, 0.007 mmol), X-Phos (3 mg, 0.007 mmol), and NaOtBu (67 mg, 0.9 mmol) in toluene (5 mL) was heated at 100° C. for 18 h. The solids were removed by filtration and the filtrate was concentrated to give an oil, which was purified by PTLC to give a beige solid (9 mg, 6%). MS (ESI): mass calcd. for C25H32FN3O3, 441.54; m/z found, 442.5 [M+H]+. 1H NMR (CDCl3): 7.46-7.43 (m, 4H), 7.38-7.33 (m, 3H), 6.90 (t, J=8.3, 1H), 5.66 (d, J=8.5, 1H), 4.07 (s, 1H), 3.70 (s, 3H), 3.20-3.18 (m, 4H), 2.65-2.63 (m, 4H), 1.68-1.55 (m, 3H), 1.49-1.42 (m, 2H), 0.93 (t, J=7.4, 6H).
