Sodium Hydroxide → HCID 11691356, compound

Participants

Reaction Steps

4.00 mL sodium hydroxide solution (1M) was added to 7.81 g (23.3 mmol) methyl 1-{3-[2-(3-benzenesulphonylamino-phenyl)-2-hydroxy-ethylamino]-3-methyl-butyl}-1H-imidazole-4-carboxylate in 8 mL tetrahydrofuran and stirred for 4 h at ambient temperature. The solvent was eliminated from the reaction mixture using the rotary evaporator and the residue was combined three times with 20 mL methanol and filtered. The combined methanolic phases were freed from solvent using the rotary evaporator and 0.390 g (0.825 mmol, 98%) 1-{3-[2-(3-benzenesulphonylamino-phenyl)-2-hydroxy-ethylamino]-3-methyl-butyl}-1H-imidazole-4-carboxylic acid were obtained as a colourless solid.
