Intermediate 26A (1 g, 3.80 mmol), ammonium chloride (1.432 g, 26.6 mmol), and zinc (1.491 g, 22.81 mmol) were added to a flask, followed by the addition of EtOH (10.0 mL) and THF (10.0 mL). The reaction mixture was stirred at room temperature for 2 hours and filtered through a pad of CELITE®. The filtrate was concentrated under reduced pressure to yield Intermediate 26 (885 mg, 100% yield). MS (ES): m/z=234.2 [M+H]+.
