実験手順

Concentrated hydrochloric acid (89.6 mL) was added to the tetrahydrofuran solution of tert-butyl 2-methyl-1-[(2R)-4-methyl-1-oxo-1-[2-oxo-8-(2-oxopyrrolidin-1-yl)-1-(thiophen-3-ylmethyl)-1,2,3,4-tetrahydroquinolin-3-ylamino]pentan-2-ylamino]-1-oxopropan-2-ylcarbamate, and the mixture was stirred at an internal temperature of 48±2° C. for 30 minutes. The mixture was neutralized with 25% aqueous sodium hydroxide solution (172 g) under cooling on an ice bath. The organic layer was separated, and then concentrated under reduced pressure, whereby the title compound (49.36 g) was yielded.
