Allyl 4-[({(2S,4R)-1-[(3-chloro-4-fluoro-1-methyl-1H-indol-5-yl)carbonyl]-4-[1-(methylsulfonyl)-4-piperidinyl]-2-pyrrolidinyl}carbonyl)amino]benzoate was prepared from the compound prepared in Example 63 following the procedures described in Example 5, 9 and 8. (Note: in the step corresponding to Example 5, allyl 4-aminobenzoate was used in place of tert-butyl 4-aminobenzoate. In the step corresponding to Example 8, the acid prepared in Example 92 was used in place of 1-(N,N′-bis(tert-butoxycarbonyl)carbamimidoyl)piperidine-4-carboxylic acid). After that, the crude allyl ester was treated with palladium(0) following the procedure described in Example 91 to give the title compound as an off-white solid.
