Procedure

A mixture of 26 mg of 2-(2-amino-5-cyclobutoxyphenyl)-N-(3-(trifluoromethyl)benzyl)isonicotinamide, 21 mg of 3-(methyl(2-morpholinoethyl)carbamoyl)benzoic acid, 27 mg of HATU, and 63 μL of DIEA in 0.2 mL of DMF was stirred at 60° C. for 2 h. The product was isolated by reverse phase chromatography eluting with 0.05% TFA in a water/acetonitrile gradient. This procedure gave 24 mg of a yellow solid. 1H NMR (400 MHz, CD3OD, ppm): δ 9.46 (t, J=5.8 Hz, 1H), 8.85 (d, J=5.3 Hz, 1H), 8.26 (s, 1H), 8.15 (d, J=9.0 Hz, 1H), 8.05 (s, 1H), 8.01 (d, J=7.8 Hz, 1H), 7.85-7.80 (m, 1H), 7.80-7.47 (m, 6H), 7.31 (d, J=2.7 Hz, 1H), 7.00 (dd, J=8.9, 2.6 Hz, 1H), 4.83-4.71 (m, 1H), 4.67 (s, 2H), 4.09 (s, 2H), 3.96 (m, 2H), 3.77 (m, 4H), 3.52 (t, J=4.9 Hz, 2H), 3.24 (s, 2H), 3.07 (s, 3H), 2.59-2.39 (m, 2H), 2.25-2.04 (m, 2H), 1.93-1.60 (m, 2H).
