Participants

Reaction Steps

Subsequently, to the reaction mixture was added a solution of (2R)-1-acetoxy-2-acetylamino-2-methyl-4-[5-(3-bromoprop-1-ynyl)furan-2-yl]butane (0.3050 g, 0.82 mmol) obtained in Example (22b) in N,N-dimethylformamide (4 ml) with stirring under ice-cooling, and then the resulting mixture was stirred at room temperature for 30 minutes. After stirring, saturated aqueous ammonium chloride solution was added to the reaction mixture to quench the reaction, and then the reaction mixture was diluted with water and ethyl acetate and extracted with ethyl acetate. The extract was washed successively with water and saturated aqueous sodium chloride solution and dried over anhydrous sodium sulfate. After filtration, the solvent was removed in vacuo, and the residue was purified by chromatography on a silica gel column using a mixed solvent of dichloromethane and acetone (10:1) as the eluent to afford the title compound (0.3188 g, yield: 93%).
