実験手順
According to the procedure described in the synthesis method of Compound IV-1, (S)-(9H-fluoren-9-yl)methyl 3-(4-tert-butoxyphenyl)-1-((2,2-diethoxyethyl)(pyridin-2-ylmethyl)amino)-1-oxopropan-2-ylcarbamate (Compound III-16) (3.12 g, 4.6 mmol) was treated with piperidine and the obtained residue was purified by silica gel column chromatography (eluent: n-hexane:ethyl acetate=9:1, chloroform:methanol=100:0 and 8:2) to obtain the title compound (1.97 g, 97%).
