실험 절차

(3S)—N,N-Dimethylpyrrolidin-3-amine (0.092 mL, 0.72 mmol) was added to a suspension of 5-chloro-N-(4-fluoro-2-methoxy-5-nitrophenyl)-4-pyrazolo[1,5-a]pyridin-3-ylpyrimidin-2-amine (Intermediate 20, 250 mg, 0.60 mmol) and DIPEA (0.125 mL, 0.72 mmol) in DMA (3 mL) and the mixture was heated at 140° C. in a microwave for 0.5 h. The mixture was then diluted with CH3OH and absorbed onto an SCX column. The column was washed with CH3OH and then eluted with 1:1 7M methanolic ammonia in CH2Cl2. Appropriate fractions were concentrated and further purification by FCC, eluting with 2% 7N methanolic ammonia in CH2Cl2 gave the title compound (300 mg, 98%) as an orange foam; 1H NMR: 1.75-1.95 (1H, m), 2.09-2.30 (7H, m), 2.72-2.87 (1H, m), 3.11-3.27 (3H, m), 3.42-3.56 (1H, m), 3.90 (3H, s), 6.57 (1H, s), 7.13 (1H, t), 7.26-7.41 (1H, m), 8.09 (1H, s), 8.28-8.50 (2H, m), 8.67 (1H, s), 8.84 (1H, d), 8.95 (1H, s); m/z: ES+ MH+ 509.5.
