Reaction Steps
A mixture of N-ethyl-2-phenyl-2-piperidin-4-yl-acetamide (90 mg, 0.3 mmol), 4-bromo-N-(1-ethyl-propyl)-3-fluoro-benzamide (prepared as in Example 113, Step A; 120 mg, 0.4 mmol), Pd2(dba)3 (6 mg, 0.007 mmol), X-Phos (3 mg, 0.006 mmol), and NaOtBu (70 mg, 0.7 mmol) in toluene (3 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 white solid (2 mg, 1%). MS (ESI): mass calcd. for C27H36FN3O2, 453.59; m/z found, 454.5 [M+H]+. 1H NMR (CDCl3): 7.69-7.67 (m, 2H), 7.60-7.58 (m, 2H), 7.44-7.43 (m, 1H), 7.41 (s, 1H), 7.36-7.31 (m, 4H), 6.89 (t, J=8.5, 1H), 5.64-5.62 (m, 1H), 5.48-5.45 (m, 1H), 3.99-3.96 (m, 1H), 3.74-3.70 (m, 1H), 3.56-3.53 (m, 1H), 3.44-3.41 (m, 1H), 3.36-3.30 (m, 1H), 3.21-3.15 (m, 1H), 2.91-2.88 (m, 1H), 2.80-2.75 (m, 1H), 2.64-2.58 (m, 1H), 2.29-2.26 (m, 1H), 2.04-2.00 (m, 1H), 1.65-1.61 (m, 1H), 1.49-1.43 (m, 1H), 1.27-1.23 (m, 1H), 1.09 (t, J=7.3, 3H), 0.93 (t, J=7.4, 6H).
