実験手順
The alcohol (140 mg) obtained in Example 2A was stirred with triethylsilane (1.0 mL) and trifluoroacetic acid (1.5 mL) in dichloromethane (5 mL) for 4 hours. The solvents were removed. The residue was diluted with toluene (5 mL) and then concentrated. This dilution-concentration process was repeated three times. Purification with preparative TLC (50% EtOAc/Hexanes) gave the final product. It was converted to the hydrochloride salt with 1N HCl in ether to yield 65 mg of the salt. MP: 217-219° C. MS: 344 (M+H).
