Reaction Steps

2-(3,4-Dichlorophenyl)-3-(1H-imidazol-4-yl)-1-[4-(7H-pyrrolo[2,3-d]pyrimidin-4-yl)-piperazin-1-yl]-propan-1-one was prepared by substituting 5-piperazin-1-yl-1H-indazole with 4-Piperazin-1-yl-7H-pyrrolo[2,3-d]pyrimidine dihydrochloride and substituting (D)-Boc-4-chlorophenylalanine with 2-(3,4-Dichlorophenyl)-3-(1H-imidazol-4-yl)-propionic acid in Example B-1, Step 2. The free amine was converted to HCl salt by treatment with HCl in Ether. 1H NMR (CD3OD, 400 MHz) δ 8.76 (s, 1H), 8.32 (s, 1H), 7.52 (m, 2H), 7.38 (s, 1H), 7.29 (m, 2H), 6.92 (s, 1H), 4.58 (m, 1H), 3.70-4.20 (m, 7H), 3.63 (m, 1H), 3.43 (m, 1H), 3.16 (m, 1H).
