Participants

Reaction Steps

A solution of the free base (0.25 g, 0.47 mmol) from example 93 in ethanol/THF (50 mL/50 mL) was treated with 1N NaOH (14.1 mL, 14.1 mmol) and refluxed with stirring for 1 h, the reaction was neutralized with 1N HCl (13.6 mL, 13.6 mmol, 29 eq), and concentrated in vacuo. The resulting residue was slurried in ether (30 ml) and anhydrous HCl in ether (30 ml) was added. The resulting slurry was concentrated in vacuo. The residue was dissolved in EtOAc and filtered. The filtrate was concentrated in vacuo to provide 0.08 g (35%) of a tan solid. MS (FD+): m/z 463. Anal Calcd for C27H31N20O5Cl: C, 64.99; He 6.26; N, 5.61. Found: C, 65.29; H, 6.55; N, 5.35.
