Versuchsvorschrift

A solution of {3-(5-chloro-2-difluoromethoxyphenyl)-4-[(pyrazolo[1,5-a]pyrimidine-3-carbonyl)amino]pyrazol-1-yl}acetic acid (20.0 g, 43.2 mmol) in DMF (150 mL) was treated with DIPEA (6.7 g, 5.2 mmol), cis-2-methyloctahydropyrrolo[3,4-c]pyrrole (6.27 g, 49.7 mmol) and HATU (18.9 g, 49.7 mmol) and the mixture left to stir at room temperature for 1 hour. The reaction mixture was diluted with 0.5M aqueous K2CO3 solution and extracted with ethyl acetate (×2). The combined organic extract was washed with water (×2) and brine, dried (Na2SO4) and evaporated to afford a solid. The resultant solid was purified by flash chromatography on silica eluting with 0-10% 2M NH3/MeOH in DCM. Collecting appropriate fractions, followed by evaporation gave the title compound as a cream solid (17.1 g, 69%). LCMS (Method 5) [M+H]+=570.9, RT=2.82. 1H NMR (400 MHz, DMSO-d6) δ: (ppm) 9.70 (s, 1H), 9.30 (dd, 1H, J=7.0, 1.6 Hz), 8.62-8.63 (m, 2H), 8.27 (s, 1H), 7.59 (dd, 1H, J=8.8, 2.7 Hz), 7.52 (d, 1H, J=2.7 Hz), 7.42 (d, 1H, J=8.8 Hz), 7.25 (dd, 1H, J=7.0, 4.2 Hz), 7.11 (t, 1H, J=73.3 Hz), 5.07 (d, 2H, J=5.9 Hz), 3.69 (dd, 1H, J=10.8, 8.6 Hz), 3.56 (dd, 1H, J=12.2, 8.8 Hz), 3.36 (dd, 1H, J=10.8, 4.4 Hz), 3.22 (dd, 1H, J=12.3, 4.5 Hz), 2.45-2.46 (m, 3H), 2.37-2.39 (m, 3H), 2.17 (s, 3H).
