実験手順
To a solution of 3-Amino-5-(1-methyl-1H-tetrazol-5-yl)-benzoic acid ethyl ester (250 mg) in THF (5 ml) at 0° C. was added pre-cooled 1M LiAlH4 solution in THF (2 ml) dropwise. This was stirred for 3 h. The reaction mixture was poured onto ice-water and extracted into EtOAc. The organic layer was separated, dried and concentrated in vacuum. Flash chromatography (100:0 to 95:5 gradient DCM:MeOH) afforded the title compound (70 mg).
