Reaction Steps

Under nitrogen, to (S)-2-(1-aminopropyl)-5-fluoro-3-phenylquinazolin-4(3H)-one (27 mg, 0.091 mmol, 1.0 equiv) in t-BuOH (0.5 mL) at 23° C. is added 7-chloro-3H-imidazo[4,5-b]pyridine (21 mg, 0.14 mmol, 1.5 equiv) and diisopropylethylamine (63 μL, 0.36 mmol, 4.0 equiv). After stirring for 48 hr at 120° C. in a sealed tube, the reaction mixture is concentrated in vacuo and the residue is purified by preparative TLC eluting with CH2Cl2/MeOH to afford the title compound (Compound 4A).
