Reaction Steps
The title compound was prepared in analogy to the procedure described in Step 57.1 using 5-amino-1,3-dimethylpyridin-2(1H)-one (Step 20.2), 4-chlorobenzaldehyde and ethyl 2,4-dioxohexanoate under reflux for 7 hr. The crude product was purified by silica gel chromatography (hexane/CH2Cl2/MeOH 40:60:10 to 0:60:10). tR: 0.82 min (LC-MS 2); ESI-MS: 387 [M+H]+ (LC-MS 2).
