Versuchsvorschrift

N,N-dimethylazetidin-3-amine (Intermediate 26, 144 mg, 0.83 mmol) was added to a suspension of 5-chloro-N-(4-fluoro-2-methoxy-5-nitrophenyl)-4-(1H-indol-3-yl)pyrimidin-2-amine (Intermediate 76, 312 mg, 0.75 mmol) and DIPEA (0.460 mL, 2.64 mmol) in 2,2,2-trifluoroethanol (5 mL). The mixture was heated in a microwave at 140° C. for 1 h. The cooled mixture was purified by ion exchange chromatography, using an SCX column and eluting with 7M methanolic ammonia. Appropriate fractions were combined and concentrated in vacuo onto silica. Further purification by FCC, eluting with 0-4% 7N methanolic ammonia in CH2Cl2 gave the title compound (347 mg, 93%) as an orange solid after trituration with diethyl ether; 1H NMR: 2.14 (6H, s), 3.09-3.18 (1H, m), 3.76 (2H, dd), 3.89 (3H, s), 4.01-4.11 (2H, m), 6.28 (1H, s), 6.98 (1H, t), 7.13-7.20 (1H, m), 7.46 (1H, d), 8.15 (1H, s), 8.23 (1H, d), 8.37 (1H, s), 8.47 (1H, s), 8.49 (1H, s), 11.84 (1H, s); m/z: ES+ MH+ 494.16.
