실험 절차

N1,N1,N2-Trimethylethane-1,2-diamine (83 mg, 0.82 mmol) was added to a mixture of N-(4-fluoro-2-methoxy-5-nitrophenyl)-4-(1H-indol-3-yl)pyrimidin-2-amine (Intermediate 68, 409 mg, 0.74 mmol), DIPEA (0.259 mL, 1.48 mmol) and DMA (3 mL). The resulting mixture was heated in a microwave at 140° C. for 0.5 h. Part-purification was achieved by ion exchange chromatography, using an SCX column (20 g) and eluting with 0.35 M methanolic ammonia. Appropriate fractions were concentrated in vacuo to provide an orange/brown gum. This gum was triturated with ethanol (15 mL) to give a solid which was collected by filtration and dried under vacuum to give the title compound (275 mg, 80%) as an orange solid; 1H NMR: 2.18 (6H, s), 2.45-2.55 (2H, m), 2.87 (3H, s), 3.25-3.30 (2H, m), 3.97 (3H, s), 6.87 (1H, s), 7.08 (1H, t), 7.18 (1H, t), 7.29 (1H, d), 7.46 (1H, d), 8.03 (1H, s), 8.33 (3H, dd), 8.66 (1H, s), 11.80 (1H, s); m/z: ES+ MH+ 462.34.
