Reaction Steps

To N-(2-(ethyloxy)-4-{1-[2-(methylsulfonyl)ethyl]-4-piperidinyl}phenyl)-2,2,2-trifluoroacetamide (1.4 g, 3.3 mmol) in THF (25 mL) and H2O (25 mL) was added LiOH (0.21 g, 5.0 mmol). The mixture was stirred for two h and then more LiOH (0.21 g, 5.0 mmol) was added. After stirring for one h, the product was extracted with EtOAc. The organic layer was dried (MgSO4), filtered and rotovaped to provided the title compound of step G as a colorless oil (1.0 g, 3.1 mmol, 94%). 1H NMR (400 MHz, DMSO-d6) δ 6.66-6.56 (m, 3H), 4.02 (q, J=7.0 Hz, 2H), 3.15 (t, J=6.6 Hz, 2H), 3.03 (s, 3H), 2.99 (d, J=11.5 Hz, 2H), 2.88 (t, J=6.6 Hz, 2H), 2.42-2.32 (m, 1H), 2.13 (dd, J=11.9, 11.7 Hz, 2H), 1.82 (d, J=13.0 Hz, 2H), 1.70-1.58 (m, 2H), 1.39 (t, J=7.0 Hz, 3H).
