Reaction Steps

Compound 6-(4-(azetidin-3-yl)phenylamino)-4-(2,3-difluorobenzylamino)nicotinamide (Example 212) (35 mg, 0.08 mmol) was stirred in 4 mL DMF with DIEA (300 μL) at 120° C. in a sealed tube for three days. The mixture was acidified with 0.5 mL TFA and subjected to reverse phase preparative HPLC to isolate the title compound (11 mg). MS found for C23H21F2N5O2 as (M+H)+ 438.4. UV: λ=259 nm. 1H NMR: (CD3OD) δ 8.17 (1H, s), 8.02 (1H, s), 7.44 (2H, dt, J=8.0; 1.6 Hz), 7.24 (1H, m), 7.17 (2H, dt, J=8.4; 1.6 Hz), 7.14 (1H, m), 7.11 (1H, m), 5.82 (1H, s), 4.68 (1H, t, J=8.0 Hz), 4.56 (2H, s), 4.46 (1H, m), 4.27 (1H, m), 4.05 (2H, m) ppm.
