Versuchsvorschrift

In 5 ml of a mixed solvent of chloroform:acetic acid=1:1, 0.1101 g (0.5 mmols) of 3-(diethoxyphosphoryl)thiophene was dissolved, to which 0.2362 g (1.05 mmols) of commercially available N-iodosuccinimide was added at room temperature. Thereafter, the reaction mixture was stirred at room temperature for 4 days. After the reaction, a disodium hydrogen phosphate/sodium dihydrogen phosphate buffer solution, adjusted to pH=7, was added, followed by extraction with chloroform. The organic phase was washed with a 0.2N sodium hydroxide aqueous solution and dried over anhydrous sodium sulfate. The solvent was removed, and the resulting crude product was purified with a PTLC plate (developed with ethyl acetate:hexane 1:1) to obtain the specified substance in the form of a yellow oil at a yield of 0.1263 g (yield: 73%). The thus obtained substance was used as it is for reaction in Example 12(9).
