Procedure

Diethyl azodicarboxylate (DEAD) (139 μL, 0.88 mmol) was added dropwise to a solution of 5,11-dihydro-2,5-dimethyl-11-ethyl-8-(2-hydroxyethyl)-6H-dipyrido[3,2-b:2′,3′-e] [1,4]diazepin-6-one (110 mg, 0.35 mmol), 4-hydroxyquinoline (128 mg, 0.88 mmol) and Ph3P (231 mg, 0.88 mmol) in THF (3.5 mL) at room temperature. The mixture was stirred at room temperature for 16 h. The reaction mixture was diluted in EtOAc (60 mL) and the solution was successively washed with 1 N aqueous NaOH (3×10 mL) and brine (15 mL) then was dried (MgSO4), filtered and concentrated under reduced pressure. The residue was purified by flash chromatography (EtOAc then EtOAc:MeOH, 9.5:0.5) to give the title compound (57 mg, 37% yield) as a white solid: MS (ESI) m/z 440 (MH)+.
