Sodium Carbonate → 5-(3-Methyl-2-oxo-2,3-dihydro-benzooxazol-5-yl)-pyridine-3-carbaldehyde

Participants

Reaction Steps

A mixture of 5-Bromo-3-methyl-3H-benzooxazol-2-one (684 mg, 3 mmol), 5-(4,4,5,5-Tetramethyl-[1,3,2]dioxaborolan-2-yl)-pyridine-3-carbaldehyde (699.2 mg, 3 mmol), polymer supported PalladiumTetrakis (0.11 mmol/g, 682 mg, 0.075 mmol), Na2CO3 (2 M in eater, 3 mL, 6 mmol) in DME (6 mL) was heated to reflux for overnight. After filteration and concentration, the residue was purified by flash column and yielded yellow solid. ESI-MS m/z: 255.0 [M+1]+, Retention time 1.03 min.
