Versuchsvorschrift

A solution of 6-((cyclopropylmethyl)(propyl)amino)pyrimidine-4-carboxylic acid (Intermediate 21, 31 mg; 0.13 mmol) in DCM (5 ml) was treated with tert-butyl 5-amino-3-(3-methoxy-3-oxopropyl)-1H-indazole-1-carboxylate (Intermediate 45, 35 mg; 0.11 mmol) and polymer-supported Mukaiyama reagent (300mg). After stirring at RT for 3 hours the mixture was filtered and washed with water. 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 tert-butyl 5-(6-((cyclopropylmethyl)(propyl)amino)pyrimidine-4-carboxamido)-3-(3-methoxy-3-oxopropyl)-1H-indazole-1-carboxylate. The intermediate was redissolved in DCM (2 ml) and treated with TFA (1 ml) and water (1 drop). After stirring at RT for 3 hours the solvent was removed in vacuo. The residue was partitioned between DCM and saturated sodium bicarbonate solution. The separated 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 an off-white solid.
