Lithium hydroxide, monohydrate → HCID 178524335, compound

Participants

Reaction Steps

To a solution of methyl 3-(1-(2-cyanoethyl)-1H-tetrazol-5-yl)benzoate (180 mg, 0.7 mmol) in 20 mL of THF cooled to 0° C. was added dropwise a solution of lithium hydroxide monohydrate (50 mg, 2.1 mmol) in 5.0 mL of water. The reaction mixture was stirred at RT for 16 h. THF was removed under reduced pressure to give a yellow oil which was diluted with 10 mL of 1 N HCl. The aqueous phase was extracted with EtOAc (2×25 mL), and the extracts were combined, dried over Na2SO4, and concentrated to afford 100 mg (58% yield) of 3-(1H-tetrazol-5-yl)benzoic acid. MS found: (M+H)+=191.
