Procedure

Using a similar procedure to that described in Example 185, but starting from methyl 4-(6-aminoindolin-1-ylmethyl)-3-methoxybenzoate and 2-cyclopentylacetic acid, there was obtained methyl 4-[6-(2-cyclopentylacetamido) indolin-1-ylmethyl]-3-methoxybenzoate in 26% yield as an off-white solid, partial NMR: 2.3 (br s,3H,CHCH2), 3.0 (t,2H,H3 -indoline), 3.4 (t,2H,H2 -indoline).
