Procedure

The reaction mixture consisting of 206 (300 mg, 0.538 mmol), ammonium chloride (24.75 mg, 0.463 mmol) and iron powder (255 mg, 4.57 mmol) in ethanol (6 mL)/water (3.0 mL) was heated to reflux for 1 h. The reaction mixture was filtered while hot and concentrated. The residue was purified by Biotage (MeOH/DCM, 0-20%, SNAP 25 g cartridge) to give the title compound 207 (133 mg, 0.252 mmol, 47% yield) as a white solid. MS: 528 (MH)+.
