DIAD (60 μL, 0.31 mmol) was added dropwise to a solution of 11-ethyl-5,11-dihydro-8-(2-hydroxyethyl)-5-methyl-6H-dipyrido[3,2-b:2′,3′-e][1,4]diazepin-6-one (75.8 mg, 0.25 mmol), ethyl 5-(4-hydroxyphenyl)-2-methyl-3-furanecarboxylate (75 mg, 0.30 mmol) and PPh3 (80.0 mg, 0.30 mmol) in THF (3 mL) at 25° C. The reaction mixture was stirred at 25° C. for 48 h. The mixture was concentrated under reduced pressure. The residue was purified by flash chromatography (Hexane:EtOAc, 3:2) to give the title compound (64 mg, 48% yield) as yellow oil.
