To methyl 6-((4-amino-6-chloropyrimidin-5-yl)ethynyl)nicotinate (50 mg, 0.17 mmol) (prepared according to the procedure in Example 3 above) in NMP (5 mL) was added (S)-2-(1-aminoethyl)-5-chloro-3-phenylquinazolin-4(3H)-one (62 mg 0.21 mmol) (prepared according to the procedure in Example 2A above), KF (33 mg 0.35 mmol), and Hunig's base (0.15 ml, 0.21 mmol). After stirring overnight at 120° C. the reaction was cooled to rt. Water was added. The precipitate was filtered, and then dissolved in DCM. Purification on silica with 0 to 100% EtOAc in hexanes then 0 to 20% MeOH in EtOAc gave material that required further purification. Purification on a reverse phase system run from 0 to 95% ACN in water (0.1% TFA) gave (S)-methyl 6-((4-amino-6-(1-(5-chloro-4-oxo-3-phenyl-3,4-dihydroquinazolin-2-yl)ethylamino)pyrimidin-5-yl)ethynyl)nicotinate.
