A solution of 4-[({6-[cyclohexyl(cyclopropylmethyl)amino]pyrimidin-4-yl}carbonyl)amino]-3-methylbenzenesulfonyl chloride (Intermediate 20, 50 mg; 0.11 mmol) in THF (5 ml) was treated with polymer-supported-diisopropylethylamine (60.7 mg; 0.22 mmol) and dimethylamine (8 μl; 0.13 mmol, Aldrich) and the reaction mixture was stirred at room temperature for three hours. The resin was filtered and the solvents were evaporated to give a residue, which was purified by column chromatography (silica) using as eluent petroleum ether/EtOAc to afford the title compound as a yellow oil.
