Participants

Reaction Steps

The product from Example 99C (0.67 g, 1.23 mmol) was dissolved in ethanol (15 mL) and cooled in an ice bath. Bismuth trichloride (0.245 mL, 3.68 mmol) was added and a slurry formed to which was added sodium borohydride (0.743 g, 19.7 mmol) portionwise causing a black precipitate to form. This mixture was stirred at ambient temperature for 20 minutes, then re-cooled and quenched with methanol (2 mL), stirring for 10 min before filtering through celite. The filtrated was concentrated to give the title compound.
