実験手順

(3R)—N,N-dimethylpyrrolidin-3-amine (255 mg, 2.24 mmol) was added to a suspension of N-(4-fluoro-2-methoxy-5-nitrophenyl)-5-methyl-4-(1-methylindol-3-yl)pyrimidin-2-amine (Intermediate 79, 414 mg, 1.02 mmol) in DMA (4 mL) and the mixture was heated in a microwave at 140° C. for 0.5 h. The mixture was then concentrated in vacuo and the residue was dissolved in EtOAc (50 mL). Purification by ion exchange chromatography, using an SCX column and eluting with 0.35M methanolic ammonia provided semi-purified material after concentration of appropriate fractions in vacuo. Purification by FCC, eluting with 1-8% CH3OH in CH2Cl2 gave the title compound (330 mg, 65%) as an orange dry film; 1H NMR: 1.75-1.86 (1H, m), 2.13-2.19 (1H, m), 2.21 (6H, s), 2.37 (3H, s), 2.75 (1H, s), 3.10-3.20 (2H, m), 3.21-3.27 (1H, m), 3.46 (1H, td), 3.90 (3H, s), 3.94 (3H, s), 6.56 (1H, s), 7.03 (1H, t), 7.21-7.26 (1H, m), 7.49 (1H, d), 7.94 (1H, s), 8.05 (1H, s), 8.23 (1H, s), 8.37 (1H, d), 8.39 (1H, s); m/z: ES+ MH+ 502.33.
