실험 절차
tert-Butyl{1-[2-(7-methoxy-2-oxoquinolin-1(2H)-yl)propyl]piperidin-4-yl}carbamate (Intermediate 119, 500 mg, 1.23 mmol) was reacted as described for Intermediate 106. The crude trifluoro acetate of the title compound was obtained as a yellow oil, 866 mg (quantitative), and used without further purification for the next step.
