실험 절차

A quantity of 10.88 g (78.73 mmol) of potassium carbonate was dried hot in an HV, left to cool under argon to RT and admixed with 127 ml of THF and also with 5.45 g (13.12 mmol) of the sulphonyl compound from Example 10A. The mixture was stirred at reflux for 16 h under argon. The mixture was cooled to RT and then filtered through Celite. The latter was rinsed with THF. The entire filtrate was freed from the volatile components on a rotary evaporator and then in an HV, to give 3.63 g (100% of theory) of the title compound.
