To a solution of 236 (45 mg, 0.122 mmol) in acetic acid (4 mL) at 100° C., was added iron powder (34 mg, 0.611 mmol). The reaction mixture was stirred for 5 minutes, filtered through a celite pad and concentrated under reduced pressure to afford title compound 237 (20 mg, 48% yield, crude) as a yellow oil that was used in the next step without further purification.
