The title compound was prepared in analogy to the procedure described in Example 57 using 4-acetyl-5-(4-chlorophenyl)-1-(3,8-dimethyl-[1,2,4]triazolo[4,3-a]pyridin-6-yl)-3-hydroxy-1H-pyrrol-2(5H)-one (Step 90.1) and 5-hydrazinyl-1-methyl-1H-pyrazole (Step 74.2). The crude material was purified by silica gel column chromatography (1% ammonia/7.5% MeOH/CH2Cl2) and triturated in Et2O. tR: 0.92 min (LC-MS 2); ESI-MS: 473 [M+H]+ (LC-MS 2); Rf=0.34 (1% ammonia/7.5% MeOH/CH2Cl2); 1H NMR (400 MHz, DMSO-d6) δ ppm 2.06 (s, 3H) 2.43 (s, 3H) 2.60 (s, 3H) 3.85 (s, 3H) 6.55 (s, 1H) 6.58-6.68 (m, 1H) 7.31 (s, 1H) 7.37 (m, J=8.6 Hz, 2H) 7.45 (m, J=8.6 Hz, 2H) 7.56 (d, J=2.4 Hz, 1H) 8.44 (s, 1H).
