The title compound was prepared using an analogous procedure to that described in Example but using 4-(4-chlorophenyl)-1-cyclopropyl-3-(methoxymethyl)-4,5-dihydropyrrolo[3,4-c]pyrazol-6(1H)-one (Step 130.4) and 5-bromo-1,3-dimethyl-2-pyridone. The crude material was purified by silica gel column chromatography (CH2Cl2/MeOH 0.5-3.5%) to provide the title compound (286 mg) as a colorless solid. tR: 0.95 min (LC-MS 2); ESI-MS: 439.1 [M+H]+ (LC-MS 2); Rf=0.48 (CH2Cl2/MeOH 9:1); 1H NMR (400 MHz, DMSO-d6) δ ppm 1.00-1.07 (m, 2H) 1.20-1.27 (m, 2H) 1.91 (s, 3H) 3.02 (s, 3H) 3.34 (s, 3H) 3.81-3.89 (m, 1H) 3.97 (d, J=12.51 Hz, 1H) 4.20 (d, J=12.51 Hz, 1H) 6.09 (s, 1H) 7.20-7.28 (m, 2H) 7.31-7.37 (m, 2H) 7.40-7.45 (m, 1H) 7.76 (d, J=2.74 Hz, 1H).
