Step 1: Methyl quinazoline-7-carboxylate Carbon monoxide was passed into a solution of 7-bromoquinazoline (250 mg, 1.20 mmol), sodium carbonate (320 mg, 2.96 mmol) and [1,1'-bis(diphenylphosphino)ferrocene]palladium(II) chloride (90.0 mg, 0.120 mmol) in methanol (10 ml). The reaction mixture was stirred at 60° C. for 2.5 h, and then evaporated in vacuo. The residue was purified via flash chromatography on silica gel (solvent gradient: 0-10percent methanol in DCM) to yield 180 mg (80percent) of the title compound as an off-white solid. 1H NMR (300 MHz, DMSO-d6) delta 9.78 (s, 1H), 9.44 (s, 1H), 8.55 (s, 1H), 8.35-8.32 (d, J=8.4 Hz, 1H), 8.25-8.22 (d, J=8.7 Hz, 1H), 3.98 (s, 3H).
