Procedure

To a mixture of 4-chloro-6-(3-methoxyphenyl)-2-(pyridin-3-yl)quinazoline (40 mg, 0.12 mmol), 4-(3,4-dichlorophenyl)pyrrolidin-2-one (100 mg, 0.437 mmol) and Cs2CO3 (42 mg, 0.127 mmol) in dry toluene (6 mL) was added Pd(OAc)2 (3 mg, 0.01 mmol) and Xantphos (10 mg, 0.02 mmol) under a nitrogen atmosphere. The resulting mixture was stirred at 100° C. for 12 h. After cooling, the mixture was filtered through a pad of celite. The residue was purified by silica gel chromatography, eluted with petroleum ether/ethyl acetate (5:4) to give the desired product as a yellow solid. 14 mg of the desired product was obtained in a 22.5% yield, LCMS: retention time=1.802 min, [MH]+=541.0, 543.0. 1H-NMR (400 MHz, DMSO-d6): δ 9.73 (s, 1H), 9.05-9.04 (m, 1H), 8.86-8.85 (m, 1H), 8.42-8.38 (m, 2H), 8.19 (d, J=8.8 Hz, 1H), 7.89 (d, J=1.6 Hz, 1H), 7.82-7.81 (m, 1H), 7.69 (d, J=8.0 Hz, 1H), 7.58 (dd, J=8.0, 1.6 Hz, 1H), 7.50 (t, J=8.0 Hz, 1H), 7.41-7.36 (m, 2H), 7.07 (dd, J=8.0, 2.0 Hz, 1H), 4.57-4.46 (m, 2H), 4.06-4.03 (m, 1H), 3.20-3.01 (m, 2H), 3.88 (s, 3H).
