Procedure

A solution of 6-(cyclohexyl(cyclopropylmethyl)amino)pyrimidine-4-carboxylic acid (Intermediate 13, 100 mg; 0.36 mmol) in DCM (4 ml) was treated with polymer-supported Mukaiyama reagent (400 mg) followed by triethylamine (100 mL; 0.73 mmol) and 4-(4-methyl-4H-1,2,4-triazol-3-yl)aniline (Maybridge, 63.2 mg; 0.36 mmol). After stirring at RT for 24 hours the mixture was filtered and washed with saturated sodium bicarbonate solution. The organic phase was passed through a hydrophobic frit and the solvent removed in vacuo. The residue was purified by column chromatography (silica) eluting with petroleum ether containing increasing amounts of EtOAc to give the title compound as a white solid.
