Reaction Steps

(S)-tert-Butyl 3-(7-bromo-2-(2-hydroxyphenyl)quinazolin-4-ylamino)pyrrolidine-1-carboxylate (0.099 g, 0.20 mmol), trans-3-methoxy-1-propenylboronic acid pinacol ester (0.051 g, 0.23 mmol), Na2CO3 (0.066 g, 0.62 mmol), palladium tetrakistriphenyl phosphine (0.012 g, 0.011 mmol) was dissolved in a toluene (1 mL) and water (0.3 mL) and the mixture was degassed in a sealed tube. The reaction mixture was heated at 110° C. for 16 h. The reaction mixture was cooled and diluted with water (50 mL) and extracted with ethyl acetate (3×50 mL). The combined organic extracts were dried (MgSO4) and concentrated in vacuo. Further purification by silica column chromatography eluting with a gradient from 1% to 10% methanol in dichloromethane, gave the title compound as a yellow solid (0.071 g, 27%).
