실험 절차

PPh3 (83 mg, 0.32 mmol) was added to a stirred suspension of 4-(4-bromo-2-fluorophenylamino)-1,5-dimethyl-6-oxo-1,6-dihydropyridine-3-carboxylic acid (2-cyano-ethyl)-amide (51 mg, 0.12 mmol) in MeCN (1.5 mL). DIAD (0.065 mL, 0.31 mmol) and TMSN3 (0.045 mL, 0.32) were added dropwise. After 22 hours, the reaction mixture was diluted with ethyl acetate and washed with water. The aqueous layer was extracted with ethyl acetate. The combined organic extracts were dried (MgSO4) and concentrated under reduced pressure. Purification by flash column chromatography gave clean desired product (33 mg, 61%).
