Diisopropylethylamine → 2-(4-(4-ethoxy-6-((4-methoxybenzyl)oxy)pyridin-3-yl)-2-fluorophenyl)-N-(6-(1-hydroxy-2-methylpropan-2-yl)-5-(trifluoromethyl)pyridin-3-yl)acetamide

Participants

Reaction Steps

A solution of 2-(4-(4-ethoxy-6-((4-methoxybenzyl)oxy)pyridin-3-yl)-2-fluorophenyl)acetic acid (50 mg, 0.122 mmol), 2-(5-amino-3-(trifluoromethyl)pyridin-2-yl)-2-methylpropan-1-ol (28.5 mg, 0.122 mmol), HATU (92 mg, 0.243 mmol) and DIEA (0.064 mL, 0.365 mmol) in DCM (10 mL) was stirred at 25° C. After LCMS analysis showed the starting material was consumed, the mixture was washed with H2O. The organic layer was washed with brine and dried over Na2SO4 and filtered. The filtrate was concentrated to give the crude product, which was purified by preparative TLC (DCM/MeOH=20/1) to yield 2-(4-(4-ethoxy-6-((4-methoxybenzyl)oxy)pyridin-3-yl)-2-fluorophenyl)-N-(6-(1-hydroxy-2-methylpropan-2-yl)-5-(trifluoromethyl)pyridin-3-yl)acetamide (20 mg, 0.032 mmol, 26% yield): 1H NMR (400 MHz, CD3OD) δ 8.95 (br. s., 1H), 8.50 (s, 1H), 7.99 (s, 1H), 7.43-7.39 (m, 3H), 7.30-7.24 (m, 2H), 6.95-6.91 (m, 2H), 6.48 (s, 1H), 5.30 (s, 2H), 4.16-4.11 (m, 2H), 3.87-3.79 (m, 6H), 1.40-1.38 (m, 9H); ES-LCMS m/z: 628.3 (M+H).
