Participants

Reaction Steps

A solution of lithium hydroxide (18.2 mg, 0.76 mmol) in water (3 ml) was added to a solution of methyl 5-(2,4,6-trichloro-N-methylphenylsulfonamido)pentanoate (178 mg, 0.45 mmol) in THF (5 ml), and stirring was carried out for 18 h at room temperature. THF was then concentrated in vacuo, water was added to the residue, and extraction with DCM (2×20 ml) was carried out. The aqueous phase was adjusted to pH 1-2 with concentrated hydrochloric acid and extracted with ethyl acetate (3×20 ml). The combined organic extracts were dried over sodium sulfate and concentrated in vacuo.
