Procedure

A solution of ethyl 4-({4-[({6-[cyclohexyl(cyclopropylmethyl)amino]pyrimidin-4-yl}carbonyl)amino]phenyl}sulfonyl)butanoate (Example 131, 80 mg; 0.16 mmol) in THF (5 ml) was treated with 10% sodium hydroxide solution (20 ml). After stirring for 45 minutes the mixture was cooled to 0° C. and acidified with concentrated HCl. The mixture was extracted with EtOAc and the combined organic extracts washed with water, passed through a hydrophobic frit and the solvent removed in vacuo. The residue was purified by column chromatography (silica) eluting with DCM containing increasing amounts of methanol to give the title compound as a white solid (65 mg, 81%).
