Reaction Steps

A stirring mixture of (2-chloro-6-fluoro-quinazolin-4-yl)-dimethylamine (50 mg, 0.22 mmol), lithium bis(trimethylsilyl)amide (260 μL, 0.26 mmol, 1.0 M in hexanes), Pd2(dba)3 (20 mg, 0.022 mmol), 2-(dicyclohexyl)phosphinobiphenyl (19 mg, 0.053 mmol), and THF (1.0 mL) was heated in a sealed tube via microwave irradiation at 65° C. for 1.5 hours. 1.0 N aqueous HCl solution (3.0 mL) was added and the mixture was stirred at room temperature for 30 minutes. The mixture was partitioned between H2O and EtOAc. The organic portion was evaporated to dryness under reduced pressure. The obtained residue was purified via silica gel chromatography using 95% CH2Cl2/5% MeOH to obtain the desired amine as a tan solid (40 mg, 19.4 mmol, 88% yield). LC/MS (10-99%) M/Z 206.9 retention time 1.18 min.
