Yield	Reaction Conditions	Operation in experiment
35%	at 160℃; for 0.5 h; Microwave irradiation	A Biotage microwave vial was charged with 3-aminoisonicotinic acid (691 mg, 5.0 mmol), formamidine acetate (573 mg, 5.5 mmol), and ethanol (10 mL). The reaction mixture was heated in the microwave at 160 °C for 30 min, diluted with H₂0 (20 mL), and cooled to 0 °C. The suspension was filtered and the solids were washed with cold H₂0 (10 mL) to provide quinazoline A2 (259 mg, 35percent) as a white solid: LC-MS (>98percent) m/z = 148.0[M+H], R_t= 0.604.

Yield	Reaction Conditions	Operation in experiment
	With N,N-dimethyl-formamide; trichlorophosphate; In acetonitrile; at 20℃;Reflux;	To a stirred solution (B-3) (1 g, 6.7 mmol) and DMF (0.1 mL) in CH3CN (20 mL) at RT, POCl3 (10 mL) is added and the resulting mixture is stirred at reflux overnight. The mixture is allowed to cool to RT and concentrated in vacuo. The residue is diluted with water (30 mL), neutralized with saturated aqueous NaHC03 solution below 10 C to adjust the PH to 8-9 and then extracted with ethyl acetate (100 mL x 4). The combined organic layer is washed with brine, dried over Na2S04 and filtered. The filtrate is concentrated in vacuo. The residue is purified by flash column chromatography on silica gel (16-50 % ethyl acetate -petro ether) to afford compound (B-4).
