Participants

Reaction Steps

A mixture of 5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzo[c][1,2,5]oxadiazole (0.313 mmol, 77 mg), N-(5-hydroxy-2,3-dihydro-1H-inden-1-yl)propane-2-sulfonamide (0.157 mmol, 40 mg), copper (II)acetate (0.157 mmol, 28.5 mg), triethylamine (0.783 mmol, 0.110 mL, 79 mg) and 4A molecular sieves (100 mg) in DCM (1 mL) was stirred at room temperature for 60 h. The reaction mixture was filtered through dicalite and the pad washed with MeOH before the filtrate was concentrated to dryness. The residue was purified by prep HPLC to give a brown film (32. mg, 5.5%). MS (ESI): m/z [M+H]+ 374.0
