Методика

This compound was prepared using a method analogous to that of Example 8, step 8.3, 4-((S)-2-amino-3-methyl-butyryl)-piperazine-1-carboxylic acid butyl ester (prepared as described in WO2008044217) replacing piperazine-1-carboxylic acid butyl ester, phenyl-1,3-thiazole-4-carboxylic acid replacing intermediate 8.2 and using CH2Cl2 instead of CH2Cl2/THF. The compound was however purified by CC (EtOAc/Hept 0:1 to EtOAc/Hept 1:0).
