Versuchsvorschrift

N,N-Dimethylazetidin-3-amine dihydrochloride (Intermediate 26, 140 mg, 0.81 mmol) was added to a suspension of N-(4-fluoro-2-methoxy-5-nitrophenyl)-4-(1H-indol-3-yl)pyrimidin-2-amine (Intermediate 68, 406 mg, 0.74 mmol) and DIPEA (0.514 mL, 2.94 mmol) in DMA (3 mL). The mixture was heated in a microwave at 140° C. for 0.5 h. The mixture was then part-purified by ion exchange chromatography, using an SCX column (20 g) and eluting with 0.35M methanolic ammonia. Appropriate fractions were combined nad 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 (245 mg, 72%) as an orange solid; 1H NMR: 2.15 (6H, s), 3.17 (1H, dd), 3.76 (2H, dd), 3.97 (3H, s), 4.03-4.10 (2H, m), 6.29 (1H, s), 7.08 (1H, t), 7.14-7.21 (1H, m), 7.27 (1H, d), 7.45 (1H, d), 8.01 (1H, s), 8.28-8.37 (3H, m), 8.64 (1H, s), 11.79 (1H, s); m/z: ES+ MH+ 460.32.
