実験手順

To a solution 4-chloro-1H-pyrrolo[2,3-b]pyridine-5-carbaldehyde (500 mg, 2.78 mmol) in MC (9 mL) were added TsCl (556 mg, 2.91 mmol) and DMAP (509 mg, 4.17 mmol). The reaction mixture stirred for 8 hours at room temperature. The produced precipitated was filtered, washed with water and dried with nitrogen gas flow. The title product (810 mg, 87% yield) was used without further purification. MS m/z: 335 [M+1].
