Participants

Reaction Steps

The methyl 5-chloro-1-((5-((2-((tetrahydro-2H-pyran-2-yl)oxy)ethyl)thio)thiazol-2-yl)carbamoyl)spiro[indoline-3,3′-pyrrolidine]-1′-carboxylate (90.0 mg, 0.163 mmol) obtained in Example 136 was dissolved in tetrahydrofuran (1 mL) and methanol (1 mL). Thereafter, a 12 N aqueous solution of hydrochloric acid (0.2 mL) was added to the above obtained solution, and the thus obtained mixture was then stirred at room temperature for 10 minutes. Thereafter, the reaction solution was neutralized with a saturated aqueous solution of sodium hydrogen carbonate, 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 (63.0 mg, 82%) in the form of a white solid.
