実験手順
The title compound was prepared in analogy to the procedure described in Example 24 using 4-(4-chlorophenyl)-2,3-dimethyl-4,5-dihydropyrrolo[3,4-c]pyrazol-6(2H)-one (Step 25.6) and 6-bromo-3-methyl[1,2,4]triazolo-[4,3-a]pyridine. After purification by silica gel column chromatography, the resulting residue was purified by SFC (Thar 100; column: PFP, 25 cm, Ø 3 cm, 5 μm, 60 Å; gradient: 10% B for 1 min, 10-15% B in 6 min, 15-50% B in 1 min, 50% B for 1.5 min, 50%-10% B in 1 min, 10% B for 0.5 min; A: scCO2, B: MeOH; flow: 100 mL/min). The residue was triturated in Et2O. tR: 3.26 min (HPLC 1); tR: 0.77 min (LC-MS 2); ESI-MS: 393 [M+H]+ (LC-MS 2); Rf=0.37 (CH2Cl2/MeOH 9:1); 1H NMR (400 MHz, DMSO-d6) δ ppm 2.11 (s, 3H) 2.64 (s, 3H) 3.88 (s, 3H) 6.49 (s, 1H) 7.35 (s, 4H) 7.47-7.52 (m, 1H) 7.65-7.70 (m, 1H) 8.64 (s, 1H).
