Procedure

To a solution of 6-isopropyl-5′-methyl-2,2′-bipyridine-4-carboxylic acid (25.0 mg, 0.07 mmol) in DMF (0.3 mL) were added hydrochloride salt of (1R)-1-[2-(trifluoromethyl)pyrimidin-5-yl]ethanamine (22.1 mg, 0.08 mmol), HATU (38.2 mg, 0.10 mmol) and diisopropylethylamine (58.5 μL, 0.34 mmol). The mixture was stirred at ambient temperature. After 20 min, the mixture was purified by reverse phase chromatography (C-18, 95% water/acetonitrile→25% water/acetonitrile with 0.1% trifluoroacetic acid) gave the title compound (24 mg), HRMS 430.1850 (M+1). 1H NMR (400 MHz, CDCl3): δ 8.96 (s, 2H), 8.48 (s, 1H), 8.43 (d, 8.1 Hz, 1H), 8.37 (s, 1H), 7.67 (d, J=8.2 Hz, 1H), 7.63 (s, 1H), 6.96 (d, J=6.7 Hz, 1H), 5.44-5.35 (m, 1H), 3.24-3.14 (m, 1H), 2.42 (s, 3H), 1.74 (d, J=7.2 Hz, 3H), 1.37 (d, J=6.9 Hz, 6H).
