Procedure
3-(5-Bromo-thiophen-2-yl)-2(S)-{[6-(4-tert-butyl-phenoxy)-1-cyclopentylmethyl-isoquinoline-3-carbonyl]-amino}-propionic acid methyl ester (prepared in Example 38) was treated with tributyl-isopropenyl-stannane and Pd(PPh3)4 as described in the general procedure M to afford 2(S)-{[6-(4-tert-butyl-phenoxy)-1-cyclopentylmethyl-isoquinoline-3-carbonyl]-amino}-3-(5-isopropenyl-thiophen-2-yl)-propionic acid methyl ester. This was treated with Pd/C and H2 (1 atm) by the general procedure N to afford 2(S)-{[6-(4-tert-butyl-phenoxy)-1-cyclopentylmethyl-isoquinoline-3-carbonyl]-amino}-3-(5-isopropyl-thiophen-2-yl)-propionic acid methyl ester. This ester was hydrolyzed by the general procedure C to afford the title compound.
