実験手順

To a stirred solution of 4-acetyl-5-(4-chlorophenyl)-3-hydroxy-1-(4-methoxybenzyl)-1H-pyrrol-2(5H)-one (Step 71.2) (3 g, 8.07 mmol) in EtOH (50 mL) and toluene (50 mL) was added 5-hydrazinyl-1-methyl-1H-pyrazole (Step 74.2) (1.941 g, 10.49 mmol) and the resulting mixture was heated up and stirred at 115° C. for 20 hr. The reaction was quenched with a saturated aq. NaHCO3 solution and extracted with EtOAc. The combined organic layers were dried over Na2SO4 and concentrated under reduced pressure. The crude product was purified by silica gel column chromatography (hexane/EtOAc 40-50%) to afford the title product (3.15 g, 6.89 mmol, 85% yield) as yellow solid. tR: 5.60 min (HPLC 1); tR: 1.24 min (LC-MS 2); ESI-MS: 448 [M+H]+ (LC-MS 2); Rf=0.41 (hexane/EtOAc 1:1).
