A cooled (−10° C.) suspension of LiAlH4 (188 mg; 4.97 mmol) in anh. THF (30 ml) was treated with a solution of commercially available ethyl 2-methylbenzo[d]thiazole-6-carboxylate (1.000 g; 4.51 mmol) in anh. THF (20 ml). The mixture was further stirred at −10° C. for 20 min. Water (0.19 ml), 15% aq. NaOH (0.19 ml), and water (0.57 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 (2-methylbenzo[d]thiazol-6-yl)methanol as a yellow oil. LC-MS (conditions A): tR=0.45 min.; [M+H]+: 180.16 g/mol.
