15 Iron-mediated oxidative alkylamine cyclization of 17 to 5: Ferricenium hexafluorophosphate (291 mg, 0.88 mmol) and anhyd. Na2CO3 (374 mg, 3.53 mmol) were added to a solution of complex 17 (185 mg, 0.354 mmol) in degassed anhyd CH2Cl2 (15 mL) under an argon atmosphere. The resulting dark green suspension was stirred at r.t. for 3 d. During this time the color turned to orange (formation of ferrocene). The reaction mixture was filtered through a short path of Celite which was subsequently washed with CH2Cl2. Removal of the solvent from the combined filtrates and flash chromatography (hexane-EtOAc, 9:1) of the residue on silica gel provided complex 5 as light yellow crystals, yield: 158 mg (86%), mp 122 °C.
