Reaction Steps

1′-Acetyl-5-chloro-N-(5-((3-(1,3-dioxoisoindolin-2-yl)propyl)thio)thiazol-2-yl)spiro[indoline-3,3′-pyrrolidine]-1-carboxamide (0.93 g, 1.57 mmol) was dissolved in ethanol (30 mL). Thereafter, a hydrazine hydrate (0.12 g, 2.36 mmol) was added to the above obtained solution at room temperature, and the thus obtained mixture was then stirred at 90° C. for 3.5 hours. Thereafter, the reaction solution was concentrated in vacuo, and the obtained residue was then purified by silica gel column chromatography (chloroform:methanol=4:1) to obtain the captioned compound (0.56 g, 77%) in the form of a colorless solid.
