Participants

Reaction Steps

Cesium carbonate (93 mg, 0.28 mmol), (S)-2,2′-bis(diphenylphosphino)-1,1′-binaphthalene (12 mg, 0.021 mmol), tris(dibenzylideneacetone)dipalladium(0) (9 mg, 0.010 mmol), and 4-chlorobenzyl alcohol (0.039 ml, 0.28 mmol) were added to a solution of 3-benzyl-4-chloro-2-methyl-1H-pyrrolo[3,2-c]pyridine (50 mg, 0.17 mmol) prepared in Preparation 2 in toluene (3 ml). The reaction mixture was refluxed under stirring for 2 days. The reaction mixture was cooled to room temperature, filtered, and then concentrated under reduced pressure. The resulting residue was purified with silica gel column chromatography and then recrystallized in n-hexane (3 ml). The resulting solid was dissolved in ethyl ether (2 ml), saturated with hydrochloric acid gas, and then filtered to give the titled compound as a white solid. (Yield: 41.2%)
