A mixture of 1-(2-methanesulfinyl-pyrimidin-4-yl)-4-(3-methanesulfonyl-propoxy)-1H-indole (25 g, 64 mM) and 4-amino-cyclohexanecarboxylic acid ethyl ester (16.3 g, 95.3 mM) in dioxane (400 mL) and heated at 110° C. for approximately 5 h. The solution was concentrated in vacuo to give a white residue. The residue was suspended in H2O, filtered and washed in H2O, and dried at 60° C. in vacuo to yield 4-{4-[4-(3-methanesulfonyl-propoxy)-indol-1-yl]-pyrimidin-2-ylamino}-cyclohexanecarboxylic acid ethyl ester (31.7 g, 99.7%).
