Reaction Steps
To a solution of 6-iodo-2-(pyridin-3-yl) quinazolin-4-ol (synthesized as described in Scheme 1 and 4, substituting 5-iodo-2-nitrobenzoic acid for 2-nitro-5-propoxy-benzoic acid) (3.00 g, 8.6 mmol, 1.0 eq.), Pd(OAc)2 (48 mg, 0.21 mmol, 0.025 eq.) and PPh3 (113 mg, 0.43 mmol, 0.05 eq.) in DMF (8 mL) was added methyl acrylate (3.22 g, 25.8 mmol, 3.0 eq.) and DIPEA (1.22 g, 9.46 mmol, 1.1 eq.) under Ar atmosphere. The mixture was stirred at 110° C. overnight. After cooling, the mixture was filtered and the solid was washed with ethyl acetate three times to afford 1.30 g of xxxvi-a as green solid (yield 49%). LCMS m/z=308.0 (M+1) (Method B) (retention time=1.41 min).
