Procedure

To a solution of 253 (71.4 mg, 0,21 mmol) in acetic acid (2.1 mL) at 100° C., was added iron powder (59 mg, 1.05 mmol). The reaction mixture was stired for 5 minutes, filtered through a Celite® pad and concentrated under reduced pressure. The residue was purified by column chromatography, eluent EtOAc/hexane (2:1), to afford title compound 254 (27.9 mg, 40% yield). MS (m/z): 321.1 (M+1).
