CDI (7.13 g, 44.0 mmol) was added to a mixture of 4-{4-[4-(3-methanesulfonyl-propoxy)-indol-1-yl]-pyrimidin-2-ylamino}-cyclohexanecarboxylic acid (16.00 g, 33.86 mmol) in dry DMF (100 mL) heated to 40° C. under N2. After stirring for 10 min, 100 mL of DMF was added, heated to 40° C., and stirred for an additional 40 min. N,N-dimethyl-piperidin-4-ylamine (5.00 g, 38.9 mmol) was added and allowed to stir overnight at RT. The reaction mixture was concentrated in vacuo, the residue diluted with EtOAc and washed with cold H2O (4×), 5% NaOH aqueous solution (4×), H2O and brine. The organic layer was dried and the remaining solvent removed in vacuo. The product, (4-dimethylamino-piperidin-1-yl)-(4-{4-[4-(3-methane-sulfonyl-propoxy)-indol-1-yl]-pyrimidin-2-ylamino}-cyclohexyl)-methanone (Compound 275), was crystallized from EtOH/H2O as a white solid (11.9 g, 60.3%). MS M+1 (583), mp 182.4-183° C.
