Reaction Steps

To 1-fluoro-2-methyl-5-(methyloxy)-4-nitrobenzene (Example 113, Step B) (21.5 g, 116 mmol) in DMSO (100 mL) was added 2-(4-piperidinyl)ethanol (15 g, 116 mmol) and K2CO3 (48.1 g, 348 mmol). The reaction was heated in a sealed tube at 80° C. overnight. The reaction mixture was cooled to rt and poured into H2O. The resultant solid was filtered, air dried, dissolved in DCM, dried (Na2SO4), filtered, and rotovapped down to give the title compound of Step F (32.6 g, 111 mmol, 95%). 1H NMR (400 MHz, DMSO-d6) δ 7.71 (s, 1H), 6.63 (s, 1H), 4.33 (t, J=5.0 Hz, 1H), 3.85 (s, 3H), 3.39-3.49 (m, 2H), 3.23 (d, J=12.2 Hz, 2H), 2.65 (t, J=11.3 Hz, 2H), 2.14 (s, 3H), 1.72 (d, J=11.4 Hz, 2H), 1.46-1.61 (m, 1H), 1.39 (q, J=6.6 Hz, 2H), 1.25 (qd, J=12.0, 3.4 Hz, 2H).
