Reaction Steps

The title compound was prepared using an analogous procedure to that described in Example 23 using 4-(4-chlorophenyl)-1-cyclopropyl-3-(methoxymethyl)-4,5-dihydropyrrolo[3,4-c]pyrazol-6(1H)-one (Step 130.4) and 6-bromo-3,8-dimethyl-[1,2,4]triazolo[4,3-a]pyridine (Step 130.6). The reaction mixture was stirred for 16 h at 110° C. After purification by silica gel column chromatography (CH2Cl2/MeOH 1-5.5%), the resulting residue was purified by SFC (column: PPU, 25 cm, Ø 3 cm, 5 μm, 100 Å; gradient: 12% B for 1 min, 12-17% B in 6 min, 17-50% B in 1 min, 50% B for 1.5 min, 50%-12% B in 1 min, 12% B for 0.5 min; A: scCO2, B: MeOH; flow: 100 mL/min) to provide the title compound (151 mg) as a colorless solid. tR: 0.94 min (LC-MS 2); ESI-MS: 463.1 [M+H]+ (LC-MS 2); Rf=0.37 (CH2Cl2/MeOH 9:1); 1H NMR (400 MHz, DMSO-d6) δ ppm 1.03-1.11 (m, 2H) 1.23-1.31 (m, 2H) 2.42 (s, 3H) 2.61 (s, 3H) 3.06 (s, 3H) 3.84-3.92 (m, 1H) 3.99 (d, J=12.12 Hz, 1H) 4.23 (d, J=12.51 Hz, 1H) 6.46 (s, 1H) 7.28-7.35 (m, 4H) 7.37 (br. s, 1H) 8.48 (br. s, 1H).
