A mixture of prop-2-ynyl-carbamic acid tert-butyl ester (2.65 g, 17.08 mmol) and (6-Iodo-quinazolin-4-yl)-[3-methyl-4-(6-methyl-pyridin-3-yloxy)-phenyl]-amine hydrochloride (8.2 g, 16.27 mmol), dichlorobis(triphenylphosphine) palladium (II) (570 mg, 0.81 mmol), copper iodide (154 mg, 0.81 mmol), and diisopropylamine (4.78 mL, 34.16 mmol) in anhydrous THF (80 mL) was stirred at room temperature for 5 hours. After concentration, the residue was dissolved in CH2Cl2 (100 mL), washed with aqueous NH4Cl and brine, dried over sodium sulfate, and concentrated to give the crude product (7.89 g, 98%) as a light yellow solid which was then used without further purification.
