Versuchsvorschrift

A solution of acryloyl chloride (0.025 mL, 0.31 mmol) in CH2Cl2 (1 mL) was added dropwise to a stirred solution of 2-{[5-amino-4-(3-dimethylaminoazetidin-1-yl)-2-methoxyphenyl]amino}-4-pyrazolo[1,5-a]pyridin-3-ylpyrimidine-5-carbonitrile (Intermediate 122, 136 mg, 0.30 mmol) in CH2Cl2 (15 mL), which was cooled in an ice bath to approximately 0° C. The mixture was stirred for 1 h, and was then diluted with iii CH2Cl2 (50 mL) and methanol (to fully dissolve suspension). This solution was then washed with sat. NaHCO3 (100 mL) which had been diluted with water (10 mL). The aqueous wash solution was then extracted with CH2Cl2 (2×50 mL) and the combined organic solutions were dried (MgSO4) and concentrated in vacuo. Purification by FCC, eluting with 0-5% 7N methanolic ammonia in CH2Cl2 gave the title compound (136 mg, 89%) as a yellow solid; 1H NMR: 2.10 (6H, s), 3.05-3.13 (1H, m), 3.62 (2H, t), 3.74 (3H, s), 4.00 (2H, s), 5.67 (1H, d), 6.17 (1H, d), 6.27 (1H, s), 6.45 (1H, dd), 7.16 (1H, br s), 7.25 (1H, s), 7.42 (1H, br s), 7.95 (1H, br s), 8.68 (1H, s), 8.87 (1H, br s), 8.91 (1H, s), 9.28 (1H, s), 9.32 (1H, br s); m/z: ES+ MH+ 510.18.
