実験手順

N-(5-Chloro-4-pyrazolo[1,5-a]pyridin-3-ylpyrimidin-2-yl)-4-(3-dimethylaminoazetidin-1-yl)-6-methoxybenzene-1,3-diamine (Intermediate 24, 297 mg, 0.64 mmol), tris(dibenzylidene-acetone)dipalladium(0) (14.62 mg, 0.02 mmol), 2-(dicyclohexylphosphino)-2′,4′,6′-tri-1-propyl-1,1′-biphenyl (‘XPhos’, 30.5 mg, 0.06 mmol), and dicyanozinc (45.0 mg, 0.38 mmol) were placed in a microwave tube under N2. Poly(methylhydrosiloxane) (12 mg, 0.06 mmol) was then added in degassed DMA (1.92 mL). The resulting mixture was then heated at 120° C. for 2 h in a microwave. The crude mixture was loaded on to a SCX column. The column was flushed with water followed by CH3OH/CH2Cl2. The desired product was eluted from the column using 7M methanolic ammonia in CH2Cl2 and pure fractions were combined and concentrated in vacuo. The residue was dissolved in CH3OH/CH2Cl2 and 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. Purification by FCC, eluting with 0-5% CH3OH in CH2Cl2 gave the title compound (139 mg, 48%) as a brown solid after trituration with diethyl ether; 1H NMR: (100° C.) 2.18 (6H, s), 3.17 (1H, t), 3.60 (2H, t), 3.69 (3H, s), 3.87 (2H, br s), 4.00 (2H, t), 6.32 (1H, s), 6.86 (1H, s), 7.11 (1H, t), 7.34-7.46 (1H, m), 8.34 (1H, d), 8.61 (1H, s), 8.72 (1H, br s), 8.76 (1H, d), 8.90 (1H, s); m/z: ES+ MH+ 456.23.
