Reaction Conditions

Reaction Steps

All chemicals were mixed in a 50 mL round bottom flask. The solids were degassed and placed under nitrogen. Toluene was added and the mixture was stirred at 100°C for 24 h. Cooled and filtered. The filtrate was concentrated under vacuum. Crude product was mainly starting material but some product had been formed. The product was purified by silica gel chromatography using 1-4% methanol/DCM. Product was slightly more polar than starting material bromide. There was obtained 230 mg of the desired product as a solid. HNMR and LC MS ok.
