Versuchsvorschrift

A mixture of N-[4-[(3aR,6aR)-5-methyl-2,3,3a,4,6,6a-hexahydropyrrolo[3,2-c]pyrrol-1-yl]-2-methoxy-5-nitrophenyl]-5-chloro-4-pyrazolo[1,5-a]pyridin-3-ylpyrimidin-2-amine (Intermediate 36, 155 mg, 0.30 mmol), iron (100 mg, 1.79 mmol) and NH4Cl (11.2 mg, 0.21 mmol) in ethanol (12 mL) and water (4 mL) was heated at reflux for 2 h. The mixture was then cooled and filtered though decalite (a type of diatomaceous earth) and the filtrate was concentrated in vacuo to provide a brown gum. Purification by FCC, eluting with 0-5% 7N methanolic ammonia in CH2Cl2 gave the title compound (105 mg, 72%) as a gum; 1H NMR: (CDCl3) 1.76-1.80 (1H, m), 2.03-2.20 (2H, m), 2.28 (3H, s), 2.48 (1H, dd), 2.59-2.63 (2H, m), 2.76-2.98 (2H, m), 3.46 (1H, dt), 3.78 (2H, s), 3.84 (3H, s), 4.07-4.10 (1H, m), 6.73 (1H, s), 6.94 (1H, td), 7.36 (1H, ddd), 7.51 (1H, s), 7.86 (1H, s), 8.35 (1H, s), 8.54 (1H, d), 8.65 (1H, d), 8.93 (1H, s); m/z: ES+ MH+ 491.29.
