Procedure

A solution of 6-((cyclopropylmethyl)(propyl)amino)pyrimidine-4-carboxylic acid (Intermediate 21, 230 mg; 0.98 mmol) in DCM (5 ml) was treated with polymer-supported Mukaiyama reagent (400 mg) and triethylamine (0.41 ml; 2.9 mmol) followed by 1H-indazol-4-amine (Key Organics, 150 mg; 1.12 mmol). After stirring at RT for 72 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.
