Versuchsvorschrift
To a solution of methyl 2-(2-(methylsulfonyl)phenyl)-1,5-naphthyridine-3-carboxylate (1.2 g, 3.5 mmol) in DCM (30 mL) was added DIBAL-H (35 mL, 35 mmol) at −78° C. The reaction mixture was stirred for 4 h at same temperature. The reaction mixture was quenched with satd solution of ammonium chloride and extracted with EtOAc. The organic layer was concentrated in vacuo to give methyl (2-(2-(methylsulfonyl)phenyl)-1,5-naphthyridin-3-yl)methanol: LC-MS (ESI) m/z 315.0 [M+H]+. It was carried on crude for next step.
