Procedure

A solution of methyl 2-(4-(6-chloropyrimidine-4-carboxamido)-N,3-dimethylphenylsulfonamido)acetate (Intermediate 36, 123 mg; 0.30 mmol) and diisopropylamine (105.5 mL; 0.61 mmol) in methanol (4 ml) was treated with N-(cyclopropylmethyl)cyclohexanamine (45.3 mg; 0.37 mmol). The mixture was heated to 160° C. in a microwave for 1 hour and then the solvent removed in vacuo. The residue was purified by column chromatography (silica) eluting with petroleum ether containing increasing amounts of EtOAc to give methyl 2-(4-(6-(cyclohexyl(cyclopropylmethyl)amino)pyrimidine-4-carboxamido)-N,3-dimethylphenylsulfonamido)acetate which was used directly without any further purification. The residue was redissolved in methanol (10 ml) and THF (10 ml) and treated with 5 N NaOH (1 ml). After stirring at RT for 5 hours the solvent was removed in vacuo. The residue was redissolved in water (10 ml) and acidified with concentrated HCl. The aqueous phase was extracted with EtOAc and the organic extracts passed through a hydrophobic frit and the solvent removed in vacuo. The residue was triturated with petroleum ether to yield the title compound as a white solid.
