Reaction Steps

To a mixture of N-(6-acetyl-5-(trifluoromethyl)pyridin-3-yl)-2-(4-(5-ethoxy-6-((4-methoxybenzyl)oxy)pyridin-3-yl)-2-fluorophenyl)acetamide (100 mg, 0.167 mmol) in THF (10 mL) was added methylmagnesium bromide (0.167 mL, 0.502 mmol). The mixture was stirred at 0° C. for 2 h under a N2 atmosphere. Then the mixture was added to H2O and extracted with EA. The combined organic extract was washed with brine, dried over MgSO4, filtered and concentrated. The crude material was purified by preparative TLC (DCM/MeOH=15:1, Rf=0.6) to yield a yellow solid of 2-(4-(5-ethoxy-6-((4-methoxybenzyl)oxy)pyridin-3-yl)-2-fluorophenyl)-N-(6-(2-hydroxypropan-2-yl)-5-(trifluoromethyl)pyridin-3-yl)acetamide (70 mg, 0.086 mmol, 51.1% yield): 1H NMR (400 MHz, CD3OD) δ 8.87 (d, J=2.0 Hz, 1H), 8.45 (d, J=2.0 Hz, 1H), 8.09 (d, J=2.4 Hz, 1H), 7.94 (d, J=2.0 Hz, 1H), 7.44-7.40 (m, 3H), 7.29 (d, J=2.4 Hz, 1H), 6.88 (s, 2H) 6.78 (d, J=2.4 Hz, 1H), 5.35 (s, 2H), 4.17-4.11 (m, 2H), 3.83 (s, 2H), 3.77 (s, 3H), 1.59 (s, 6H), 1.41 (t, J=7.1 Hz, 3H); ES-LCMS m/z 494.2 (M-PMB+H).
