Hydrazine hydrate (1:1) → (2r)-2-Amino-ethanesulfonic acid (5-chloro-2-{2-[4-(4-fluoro-benzyl)-2-methyl-piperazin-1-yl]-2-oxo-ethoxy}-phenyl)-amide

Participants

Reaction Steps

To a solution of 2-(1,3-dioxo-1,3-dihydro-isoindol-2-yl)-ethanesulfonic acid (5-chloro-2-{2-[4-(4-fluoro-benzyl)-2-methyl-piperazin-1-yl]-2-oxo-ethoxy}-phenyl)-amide (0.030 g, 0.048 mmol) in EtOH (1 mL) at ambient temperature was added hydrazine hydrate (0.025 mL). The reaction was stirred overnight at ambient temperature then diluted with water and extracted with methylene chloride (2×). The combined organics were washed with saturated aqueous brine and dried over sodium sulfate, filtered and concentrated in vacuo. Purification via radial chromatography (2 mm plate) gave the title compound (0.014 g).
