A cooled (−10° C.) suspension of LiAlH4 (207 mg; 5.47 mmol) in anh. THF (40 ml) was treated with a solution of methyl 2-methylbenzo[d]thiazole-5-carboxylate (1.032 g; 4.97 mmol) in anh. THF (20 ml). The mixture was further stirred at −10° C. for 20 min. Water (0.20 ml), 15% aq. NaOH (0.20 ml), and water (0.60 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-5-yl)methanol as a yellow oil. LC-MS (conditions A): tR=0.48 min.; [M+H]+: 180.19 g/mol.
