A mixture of the lithium salt of 2-(quinazolin-6-ylamino)-benzoic acid (Step B, 533 mg, 0.72 mmol), 4,4-dimethyl-1,2,3,4-tetrahydro-quinolin-7-ylamine (127 mg, 0.72 mmol), TBTU (462 mg, 1.44 mmol) and DIEA (0.25 mL, 1.44 mmol) in 3 mL of DMF was submitted to microwave irradiation (80° C., 30 min). Water (5 mL) was added to the mixture, and the resultant precipitate was filtered and dried. The crude material was purified with flash chromatography (SiO2, 50% EtOAc/hexane) to afford a white solid. MS (ES+): 424.0 (M+H)+. Calc'd for C26H25N5O: 423.51.
