Reaction Steps

(The method G13 is representative of method G12 also. This method can be implemented in a similar way except for substitution of the appropriate base, solvent and temperature) To a suspension of 4-chloro-6-methoxy-2-(pyridine-3-yl)quinazoline (645.2 mg, 2.375 mmol) and 2-amino-4-(4-chlorophenyl)thiazole (1050 mg, 4.98 mmol) in DMA (40 mL) was added Cs2CO3 (2430 mg, 7.46 mmol) at room temperature. The mixture was stirred at 80° C. for 9.5 h. Water was added and a precipitate formed which was collected by filtration and washed with H2O. Recrystallization from acetone/DMF/methanol gave 383.6 mg of the product in a 36% yield as yellow solid, >98% purity by 1H NMR). 1H NMR (400 MHz DMSO-d6) δ 12.52 (s, 1H), 9.78 (d, J=1.56 Hz, 1H), 8.91-8.88 (m, 1H), 8.74 (dd, J=4.74, 1.60 Hz, 1H), 8.33 (brs, 1H), 8.06 (d, J=8.56 Hz, 2H), 7.93 (d, J=9.08 hz, 1H), 7.89 (s, 1H), 7.66-7.59 (m, 2H), 7.55 (d, J=8.56 Hz, 2H), 4.01 (s, 3H).
