Participants

Reaction Steps

To a solution of diethyl (3R)-3-t-butoxycarbonylamino-3-methyl-5-[5-(5-phenylpentanoyl)furan-2-yl]pentylphosphonate (108.2 mg, 0.19mmol) obtained in Example (29d) in dichloromethane (1.9 ml) was added bromotrimethylsilane (0.255 ml, 1.93 mmol), and the resulting mixture was stirred at room temperature under a nitrogen atmosphere for 4 hours. After stirring, the reaction mixture was evaporated in vacuo, and the residue was diluted with aqueous ethanol, and then the resulting mixture was adjusted to pH 4 with aqueous ammonia and acetic acid. The crystals precipitated were collected by filtration, washed successively with water and ethanol and dried to afford the title compound (51.4 mg, yield: 66%).
