실험 절차

A mixture of N-[5-chloro-4-(1-methylindol-3-yl)pyrimidin-2-yl]-4-[(3R)-3-dimethyl-aminopyrrolidin-1-yl]-6-methoxybenzene-1,3-diamine (Intermediate 85, 324 mg, 0.66 mmol), zinc powder (4.3 mg, 0.07 mmol), tris(dibenzylideneacetone)-dipalladium(0) (60.3 mg, 0.07 mmol), dicyclohexyl(2′,4′,6′-triisopropylbiphenyl-2-yl)phosphine (‘XPhos’, 62.8 mg, 0.13 mmol), and dicyanozinc (46.4 mg, 0.40 mmol) was placed in a reaction tube under N2 and then degassed DMA (1.75 mL) was added. The resulting suspension was heated to 95° C. and stirred for 2 h. The mixture was then diluted with EtOAc and washed 5 times with water, and then with brine. The solution was the dried (MgSO4) and concentrated in vacuo. The residue was dissolved in CH3OH and was allowed to pass through a stratospheres SPE cartridge PL-Thiol MP SPE (available from Polymer Laboratories) under gravity. The resulting solution was concentrated in vacuo and the resulting residue was triturated with diethyl ether. The resulting solid was collected by filtration and washed with diethyl ether to give the title compound (184 mg, 58%) as a yellow solid; 1H NMR: (100° C.) 1.8-1.88 (1H, m), 2.03-2.11 (1H, m), 2.24 (6H, s), 2.92-2.99 (1H, m), 3.01-3.05 (1H, m), 3.06-3.11 (1H, m), 3.20 (2H, ddd), 3.69 (3H, s), 3.90 (3H, s), 4.17 (2H, br s), 6.73 (1H, s), 7.04 (1H, s), 7.10 (1H, t), 7.26 (1H, t), 7.50 (1H, d), 8.31 (1H, d), 8.42 (1H, s), 8.60 (1H, s), 8.62 (1H, s); m/z: ES+ MH+ 483.31.
