Reaction Steps

Triethylamine (100 μL) and 6-pyrollidin-1-ylpyridin-2-amine 35 (0.136 mmol) was added to a solution of 3-methyl-4-oxo-2-(3-(trifluoromethyl)phenyl)-3,4-dihydroquinazoline-8-carbonyl chloride 34 (50 mg, 0.136 mmol) in dioxane (1 mL). The reaction was stirred at 70° C. for 2 d, after which 1N HCl (4 mL) was added. The resulting precipitate was collected by filtration, rinsed with 5 mL H2O, 5 mL pentane, and dried under vacuum to give Compound 350 (40 mg, 56% yield). MS (ESI) calc. for C26H22F3N5O2: 493.17. found: 494 [M+H].
