Hydrochloric Acid → ethyl 2-[3-chloro-4-[2-[[(1S,2R)-2-hydroxy-2-(4-hydroxyphenyl)-1-methylethyl]amino]ethyl]phenoxy]-2-methylpropionate hydrochloride

Participants

Reaction Steps

To a stirred solution of ethyl 2-[3-chloro-4-[2-[[(1S,2R)-2-hydroxy-2-(4-hydroxyphenyl)-1-methylethyl]-amino]ethyl]phenoxy]-2-methylpropionate (170 mg) in ethyl acetate (7.8 ml) was added 4N hydrogen chloride in ethyl acetate solution (200 μl) at room temperature. After the solvent was removed under reduced pressure, diethyl ether was added to the residue, and collection of the insoluble material by filtration gave ethyl 2-[3-chloro-4-[2-[[(1S,2R)-2-hydroxy-2-(4-hydroxyphenyl)-1-methylethyl]amino]ethyl]-phenoxy]-2-methyl-propionate hydrochloride (175 mg).
