実験手順

A mixture of N-[4-[(3aR,6aR)-5-methyl-2,3,3a,4,6,6a-hexahydropyrrolo[3,4-b]pyrrol-1-yl]-2-methoxy-5-nitrophenyl]-4-(1-methylindol-3-yl)pyrimidin-2-amine (Intermediate 124, 256 mg, 0.51 mmol), iron powder (172 mg, 3.07 mmol) and NH4Cl (19.19 mg, 0.36 mmol) were heated in ethanol (3 mL) and water (1 mL) at reflux for 18 h. The crude mixture was then purified by ion exchange chromatography, using an SCX column. The desired product was eluted from the column using 7M methanolic ammonia and concentrated in vacuo. Further purification by FCC, eluting with 0-5% 7N methanolic ammonia in CH2Cl2 gave the title compound (198 mg, 82%) as a yellow foam; 1H NMR (CDCl3) 1.78 (1H, td), 2.07-2.13 (1H, m), 2.15 (1H, dd), 2.29 (3H, s), 2.47 (1H, dd), 2.57-2.65 (2H, m), 2.82-2.95 (2H, m), 3.45 (1H, dt), 3.85 (3H, s), 3.88 (3H, s), 4.07 (1H, ddd), 6.74 (1H, s), 7.01 (1H, d), 7.27-7.35 (2H, m), 7.38 (1H, dd), 7.55 (1H, s), 7.79 (1H, s), 8.14 (1H, s), 8.33 (1H, d), 8.45-8.52 (1H, m); m/z: ES+ MH+ 470.29.
