Reaction Steps

3-cyclopentyl-1-methyl-2-pyrazin-2-yl-1H-indole-6-carboxylic acid 5-1 (prepared using procedures described in WO 03/010141) and (E)-3-[2-(1-aminocyclobutyl)-1-methyl-1H-benzimidazol-5-yl]acrylic acid ethyl ester 4-2 were coupled, followed by saponification of the ethyl ester, using analogous procedures to those described in Example 4 to give (E)-3-(2-{1-[(3-Cyclopentyl-1-methyl-2-pyrazin-2-yl-1H-indole-6-carbonyl)amino]cyclobutyl}-1-methyl-1H-benzimidazol-5-yl)acrylic acid 5-2 (compound 4003, Table 4).
