Reaction Steps

According to the procedure described in the synthesis method of Compound IV-1, (9H-fluoren-9-yl)methyl(S)-3-(4-tert-butoxyphenyl)-1-(((S)-1,1-diethoxypropan-2-yl)(quinoxalin-5-ylmethyl)amino)-1-oxopropan-2-ylcarbamate (Compound III-12) (586 mg, 0.80 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 (288 mg, 71%).
