Versuchsvorschrift

A cooled (−10° C.) suspension of LiAlH4 (50 mg; 1.34 mmol) in anh. THF (2 ml) was treated with a solution of methyl 3-chloro-5-(pyridin-2-yl)benzoate (302 mg; 1.21 mmol) in anh. THF (1 ml). The mixture was further stirred at −10° C. for 20 min. Water (50 μl), 15% aq. NaOH (50 μl), and water (0.15 ml) were then successively added, and the resulting mixture was further stirred at rt for 1 h. Filtration, concentration to dryness under reduced pressure, and additional drying under HV afforded (3-chloro-5-(pyridin-2-yl)phenyl)methanol as a yellow oil. LC-MS (conditions A): tR=0.48 min.; [M+H]+: 220.08 g/mol.
