実験手順

N1,N1,N2-trimethylethane-1,2-diamine (80 mg, 0.79 mmol) was added to a suspension of N-(4-fluoro-2-methoxy-5-nitrophenyl)-4-(1-methylindol-3-yl)pyrimidin-2-amine (Intermediate 129, (which may be prepared by the method described for Intermediate 87); 350 mg, 0.79 mmol) and DIPEA (0.342 mL, 1.97 mmol) in 2,2,2-trifluoroethanol (5 mL). The mixture was heated in a microwave at 140° C. for 1 h. The cooled reaction mixture was purified by ion exchange chromatography, using an SCX column. The desired product was eluted from the column using 7M methanolic ammonia and appropriate fractions were combined and concentrated in vacuo onto silica. Purification by FCC, eluting with 0-4% 7N methanolic ammonia in CH2Cl2 gave the title compound (230 mg, 62%) as an orange solid; 1H NMR: 2.16 (6H, s), 2.45-2.49 (2H, t, obscured by DMSO peak), 2.86 (3H, s), 3.26 (2H, t), 3.87 (3H, s), 3.95 (3H, s), 6.85 (1H, s), 7.11 (1H, t), 7.21 (1H, d), 7.25 (1H, t), 7.52 (1H, d), 8.10 (1H, s), 8.31 (1H, d), 8.33 (1H, s), 8.36 (1H, d), 8.62 (1H, s); m/z: ES+ MH+ 476.40.
