Potassium Carbonate → HCID 59536717, compound

Participants

Reaction Steps

4.42 g (32.0 mmol) of potassium carbonate were dried in the heat under high vacuum and then cooled to RT under an atmosphere of argon. 52 ml of anhydrous THF and 2.22 g (5.33 mmol) of the compound of Example 21A were added. The reaction mixture was then stirred at reflux temperature for 16 h. After cooling to RT, the reaction mixture was filtered through Celite. The solid was washed with a little THF. The combined filtrates were freed from the solvent on a rotary evaporator and the residue was dried under high vacuum. This gave 1.38 g (94% of theory) of the title compound.
