Cesium carbonate → HCID 86690949, compound

Participants

Reaction Steps

179 mg (0.58 mmol) of the compound from Example 5A and 285 mg (0.88 mmol) of cesium carbonate were suspended in 5 ml of acetonitrile, and 340 mg (0.58 mmol) of the compound from Example 108A were added. The mixture was stirred under reflux for 4 h. The precipitated solid was then filtered off and the filtrate was concentrated under reduced pressure to a volume of about 1.5 ml. After addition of 0.5 ml of 1 N hydrochloric acid, the mixture was directly purified chromatographically [Method 19]. This gave 231 mg (65% of theory) of the target compound.
