Reaction Steps

The title compound was prepared in analogy to the procedure described for Example 23 using 4-(4-chlorophenyl)-1-(2-methoxypyridin-3-yl)-3-methyl-4,5-dihydropyrrolo[3,4-c]pyrazol-6(1H)-one (Step 71.4) and 5-iodo-1,3-dimethylpyridin-2(1H)-one (step 23.2) at 100° C. for 16 hr. Further purification by preparative achiral SFC (column Silica, gradient 22-27% in 6 min_total 11 min). tR: 4.34 min (HPLC 1); tR: 1.00 min (LC-MS 2); ESI-MS: 476 [M+H]+ (LC-MS 2); Rf=0.51 (CH2Cl2/MeOH 9:1).
