Yield	Reaction Conditions	Operation in experiment
89%	at 110℃; for 1.00 h;	Step 5. 8-Bromo-2-chloro-6-fluoroquinazolineA 0.5M suspension of 8-bromo-6-fluoroquinazolin-2-ol in phosphorus oxychloride was heated to 110 ⁰C in an oil bath. The suspension was turned to a brown color solution in 20min. LCMS data showed that the reaction was complete after 1 h. The phosphorus oxychloride was removed by concentration. The residue was mixed with ice water, and adjusted pH to 7 by adding sodium bicarbonate. Reaction mixture was extracted with ethyl acetate. Combined organic phase was washed with water, brine, dried over sodium sulfate and concentrated to give desired product in 89percent yield. ES/MS m/z 261/263 (MH⁺).

Yield	Reaction Conditions	Operation in experiment
53%	With (1,1'-bis(diphenylphosphino)ferrocene)palladium(II) dichloride; potassium carbonate; In N,N-dimethyl-formamide; at 120℃;	A mixture of <strong>[953039-63-9]8-bromo-2-chloro-6-fluoroquinazoline</strong> (500 mg, 1.91 mmol, 1 equiv), methylboronic acid (114.5 mg, 1.91 mmol, 1 equiv), K2CO3 (528.6 mg, 3.82 mmol, 2 equiv), Pd(dppf)Cl2 (139.9 mg, 0.19 mmol, 0.1 equiv) in 20 mL of DMF was stirred overnight at 120C. The reaction was then quenched by the addition of 50 mL of water, extracted with ethyl acetate (2x20 mL) and the combined organic layers concentrated. The residue was purified by silica gel chromatography with ethyl acetate/petroleum ether (1 :3) to afford the desired product as a yellow solid in 53% yield.
