To a solution of 5-chl oro-Af4-(3 -ethyl pi peri di n-4-yl )-Af4-m ethyl -Af2-(3 – methylimidazo[l,2-a]pyridin-7-yl)pyrimidine-2, 4-diamine (100 mg, 0.250 mmol) and 6- chloropyridazine-3-carbonitrile (53 mg, 0.380 mmol) in ethanol (20 mL) was added TEA (78 mg, 0.771 mmol). The mixture was stirred at rt overnight and concentrated in vacuo. The residue was purified by preparative TLC (MeOH/DCM (v/v) = 1/20) to afford the title compound as a yellow solid (86 mg, yield 68%).MS (ESI, pos. ion) m/z: 503.4 [M+H]+;1H NMR (400 MHz, DMSO-d6) d (ppm): 9.91 (s, 1H), 8.29-8.23 (m, 2H), 8.15 (s, 1H), 7.84 (d, J = 9.7 Hz, 1H), 7.41 (d, j= 9.8 Hz, 1H), 7.35 (s, 1H), 7.28 (s, 1H), 4.71 (d, j= 26.9 Hz, 2H), 4.44 (s, 1H), 3.26 (s, 2H), 2.97 (s, 3H), 2.42 (s, 3H), 1.98 (d, j = 11.6 Hz, 1H), 1.93 – 1.74 (m, 2H), 1.43 (s, 1H), 1.06 (s, 1H), 0.87 (t, j= 7.2 Hz, 3H).

To a deoxygenated mixture of 6-chloropyridazine-3-carbonitrile (100 mg, 0.717 mmol) , (4- (methylsulfonyl) phenyl) boronic acid (215 mg, 1.08 mmol) , and sodium carbonate (190 mg, 1.79 mmol) in dioxane (3 mL) and water (0.600 mL) was added PdCl2(dppf) (58 mg, 0.072 mmol) , and the resulting mixture was heated at 80 for 3 h under a nitrogen atmosphere. The mixture was cooled and filtered. The filtrate was concentrated and the residue was purified by column chromatography on silica gel (0-10MeOH/DCM) to afford the title compound. MS: m/z 260.0 (M + 1) .

As the paragraph descriping shows that 35857-89-7 is playing an increasingly important role.
