Versuchsvorschrift

According to the procedure described in the synthesis method of Compound III-5, (S)-1,1-diethoxy-N-(quinoxalin-5-ylmethyl)propan-2-amine (Compound IX-12) (1.93 g, 6.65 mmol) was coupled with (S)-2-(((9H-fluoren-9-yl)methoxy)carbonylamino)-3-(4-tert-butoxyphenyl)propanoic acid (3.36 g, 7.31 mmol) and the obtained residue was purified by Büch silica gel column chromatography (eluent: chloroform:methanol=100:0 to 98:2) to obtain the title compound (2.35 g, 48%).

Aufarbeitung
