Procedure

The mixture of compound 4-(2,3-difluorobenzylamino)-6-(4-(piperidin-4-yl)phenylamino)nicotinamide (Example 209) (50 mg, 0.11 mmol), (S)-acetyl-pyrrolidine-2-carboxylic acid (35 mg, 0.22 mmol), DIEA (180 μL, 1.1 mmol) in 4 mL NMP was stirred at RT. To it was added BOP (210 mg, 0.55 mmol). The mixture was stirred for overnight, quenched with TFA, and subjected to reverse phase preparative HPLC to isolate the title compound (64 mg). MS found for C31H34F2N6O3 as (M+H)+ 577.5. UV: λ=259 nm. 1H NMR (a pair of rotomers): (CD3OD) δ 8.13 (with 8.15, 1H, s), 7.36 (with 7.32, 2H, d, J=8.8 Hz), 7.25 (1H, m), 7.16 (1H, m), 7.13-7.07 (3H, m), 5.83 (with 5.79, 1H, s), 4.95 (1H, m), 4.65 (1H, m), 4.56 (with 4.55, 2H, s), 4.20 (1H, m), 3.66 (2H, m), 3.30 (1H, m), 2.92 (1H, m), 2.79 (1H, m), 2.27 (1H, m), 2.12 (with 2.10, 3H, s), 2.07-1.85 (5H, m), 1.68 (2H, m) ppm.
