Procedure

A solution of 6-((cyclopropylmethyl)(propyl)amino)-N-(4-formyl-2-methylphenyl)pyrimidine-4-carboxamide (Intermediate 29, 100 mg; 0.28 mmol) in DCM (5 ml) was treated with tert-butyl 2-aminopropanoate hydrochloride (227.1 mg; 1.24 mmol) and polymer supported carbonate (150 mg) followed by polymer supported triacetoxy borohydride (150 mg). After stirring for 18 hours the mixture was filtered 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 2-(4-(6-((cyclopropylmethyl)(propyl)amino)pyrimidine-4-carboxamido)-3-methylbenzylamino)propanoate which was used directly without any further purification. The residue was taken up into DCM (4.5 ml) and TFA (0.5 ml) added. After stirring at RT for 2 hours the solvent was removed in vacuo. The residue was taken up into dilute HCl and precipitated by basification to pH 3-4. The solid was removed by filtration, washed with water and dried to give the title compound as a white solid (85 mg, 71%).
