Versuchsvorschrift

A solution (0.04 M) of 3-cyclohexyl-1-[2-(dimethylamino)-2-oxoethyl]-2-(4 methoxyphenyl)-1H-indole-6-carboxylic acid (from Step 4) in DMF was treated with DIPEA (3 eq.), HATU (2 eq.) and ethyl (2E)-3-(4-{[(1-aminocyclopentyl)carbonyl]amino}phenyl)acrylate (1.1 eq.). The solution was stirred at 25° C. for 12 h. The mixture was diluted with EtOAc then washed sequentially with aqueous HCl (1N), NaOH (2 N) and brine. The dried organic layer was concentrated and the residue dissolved in a solution 1:1 of THF/H2O. The resulting solution was treated with LiOH monohydrate (3 eq.) and stirred at 50° C. for 5 h. The mixture was concentrated under reduced pressure and the residue was treated with aqueous HCl (1 N). Purification by HPLC (stationary phase: Water Symmetry C18 19×300 mm) gave the title compound (11%) as a solid. 1H NMR (400 MHz, DMSO-d6, 300K) δ 1.11-1.40 (m, 3H), 1.62-1.91 (m, 11H), 2.05-2.16 (m, 2H), 2.28-2.44 (m, 2H), 2.50-2.62 (m, 1H), 2.80 (s, 3H), 2.92 (s, 3H), 3.85 (s, 3H), 4.83 (s, 2H), 6.40 (d, J 16.0, 1H), 7.08 (d, J 8.6, 2H), 7.24 (d, J 8.6, 2H), 7.52 (d, J 16.0, 1H), 7.60 (d, J 8.3, 2H), 7.66 (d, J 8.3, 2H), 7.71 (d, J 8.3, 1H), 7.78 (d, J 8.3, 1H), 7.83 (s, 1H), 8.26 (s, 1H), 9.67 (s, 1H), 12.40 (br s, 1H); MS (ES+) m/z 691 (M+H)+.
