Reaction Steps

A 2.0 dram reaction vial was charged with 6-bromo-N-(3-chloro-4-fluorophenyl)-2-(pyridin-3-yl)quinazolin-4-amine (synthesized as described in Scheme 1 and 4, substituting 5-bromo-2-nitrobenzoic acid for 2-nitro-5-propoxy-benzoic acid and 3-chloro-4-fluoroaniline for 2-aminobenzamide) (100 mg, 0.233 mmol, 1.0 equiv), 3-(pyrrolidin-1-yl)propan-1-amine (40 mg, 0.345 mmol, 1.5 equiv), copper(I) iodide (4.4 mg, 0.023 mmol, 0.1 equiv), L-proline (5.3 mg, 0.046 nm tool, 0.2 equiv), and potassium carbonate (96 mg, 0.69 mmol, 3.0 equiv) in 1DMF (3 mL). The reaction mixture was heated at 100° C. overnight. After cooling, water was added to the reaction mixture, and the resultant precipitate was collected by filtration. The crude product was purified via prep-TLC (silica, 2000 micron plate, 95% dichloromethane-5% methanol-0.1% NH4OH) to yield the desired compound as a brown solid (17.2 mg, 15%). LCMS m/z=477.4 (M+1) (Method C) (retention time=1.68 min). 1H NMR (300 MHz, DMSO) δ 9.68 (s, 1H), 9.46 (s, 1H), 8.59 (d, J=9.4 Hz, 2H), 8.25 (dd, J=6.8, 2.6 Hz, 1H), 7.93 (dd, J=8.3, 3.5 Hz, 1H), 7.69-7.59 (m, 1H), 7.52 (dd, J=11.0, 7.1 Hz, 2H), 7.36-7.19 (m, 2H), 6.41 (s, 1H), 3.34 (m, 2H) 2.69 (m, 6H), 2.02-1.82 (m, 2H), 1.75 (bs, 4H).
