Reaction Steps

(This method is representative of method G1, G2, and G3. These three methods can be implemented in a similar way except for substitution of the appropriate solvent and temperature) The mixture of 4-chloro-2-(pyridazin-4-yl)quinazoline (10 mg, 0.041 mmol, 1 eq.) and 3,4-difluorobenzenamine (11 mg, 0.082 mmol, 2 eq.) was suspended in i-PrOH. The mixture was heated at 85° C. overnight. After cooling, the resulting precipitate was filtered and purified on HPLC (Condition C). 7.3 mg of N-(3,4-difluorophenyl)-2-(pyridazin-4-yl)quinazolin-4-amine was obtained (yield 53%). LCMS m/z=336.0 (M+1) (Method B) (retention time=1.731 min). 1H-NMR (400 MHz, DMSO-d6): δ 10.23 (s, 1H), 10.00 (dd, J=2.2, 1.3 Hz, 1H), 9.44 (dd, J=5.4, 1.2 Hz, 1H), 8.59 (d, J=8.1 Hz, 1H), 8.39 (dd, J=5.4, 2.4 Hz, 1H), 8.05-8.13 (m, 1H), 7.99 (s, 1H), 7.97 (d, J=3.6 Hz, 1H), 7.72-7.79 (m, 2H), 7.51-7.61 (m, 1H).
