実験手順

(3aR,6aR)-5-Methyl-2,3,3a,4,6,6a-hexahydro-1H-pyrrolo[3,2-c]pyrrole (Intermediate 37, 91 mg, 0.72 mmol) was added to a mixture of 5-chloro-N-(4-fluoro-2-methoxy-5-nitrophenyl)-4-pyrazolo[1,5-a]pyridin-3-ylpyrimidin-2-amine (Intermediate 20, 250 mg, 0.60 mmol) and DIPEA (0.334 mL, 1.93 mmol) in 2,2,2-trifluoroethanol (3 mL) and the mixture was heated at 140° C. in a microwave for 0.5 h. The mixture was then absorbed onto silica. Purification by FCC, eluting with 2% 7N methnaolic ammonia in CH2Cl2 gave material that was concentrated in vacuo and dissolved in CH3OH. The resulting solution was absorbed onto an SCX column and the column was washed with CH3OH then eluted with 7N methanolic ammonia. Appropriate fractions were concentrated in vacuo to give the title compound (155 mg, 49%) as a orange/red gummy solid; 1H NMR: (CDCl3) 1.89 (1H, dd), 2.04-2.19 (1H, m), 2.24 (3H, s), 2.30-2.39 (1H, m), 2.40-2.57 (2H, m), 2.68 (1H, t), 2.98-3.11 (1H, m), 3.23 (1H, t), 3.51-3.63 (1H, m), 3.97 (3H, s), 4.36-4.48 (1H, m), 6.46 (1H, s), 6.90-7.02 (1H, m), 7.31-7.43 (2H, m), 8.38 (1H, s), 8.48 (1H, dd), 8.53-8.57 (1H, m), 8.82 (1H, s), 8.93 (1H, s); m/z: ES+ MH+ 521.45.
