Versuchsvorschrift

A cooled (−10° C.) suspension of LiAlH4 (37 mg; 0.97 mmol) in anh. THF (1.5 ml) was treated with a solution of methyl 2-chloro-5-(pyridin-2-yl)benzoate (220 mg; 0.88 mmol) in anh. THF (1 ml). The mixture was further stirred at −10° C. for 20 min. Water (37 μl), 15% aq. NaOH (37 μl), and water (110 μl) 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 (2-chloro-5-(pyridin-2-yl)phenyl)methanol as a colorless solid. LC-MS (conditions A): tR=0.42 min.; [M+H]+: 219.94 g/mol.
