Reaction Steps

By working in a way similar to that described in example 1 and using 1-[(2S,3R)-3-benzyloxycarbonylamino-2-hydroxy-4-(4-methylsulfonyl-phenyl)-butanoyl]-amino-1-cyclopentanecarboxylic acid (0.4 g; 0.00077 moles), prepared as described in example 15, and Nω -benzyloxycarbonyl-L-arginine benzyl ester (0.614 g; 0.00154 moles) as starting compounds, Nα -[1-[(2S,3R)-3-benzyloxycarbonylamino-2-hydroxy-4(4-methylsulfonyl-phenyl)-butanoyl]-amino-1-cyclopentanecarbonyl]-Nω -benzyloxycarbonyl-L-arginine benzyl ester was obtained (0.207 g; 30% yield).
