Sodium Sulfite → HCID 90449956, compound

Participants

Reaction Steps

The methyl 5-chloro-1-((5-(methylthio)thiazol-2-yl)carbamoyl)spiro[indoline-3,3′-pyrrolidine]-1′-carboxylate (41.0 mg, 0.093 mmol) obtained in Example 127 was dissolved in methylene chloride (4 mL). Thereafter, meta-chloroperbenzoic acid (64.0 mg, 0.37 mmol) was added to the above obtained solution, and the thus obtained mixture was then stirred at room temperature for 2 hours. Thereafter, the reaction solution was diluted with an aqueous solution of sodium sulfite, and was then extracted with chloroform. The organic layer was washed with brine, and was then dried over anhydrous sodium sulfate, followed by concentration in vacuo. The obtained residue was purified by silica gel column chromatography (chloroform:methanol=10:1) to obtain the captioned compound (22.0 mg, 50%) in the form of a white solid.
