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 methylamine (0.25 ml, 2M in THF; 0.5 mmol) followed by polymer supported triacetoxy borohydride (150 mg). After stirring for 15 hours a further portion of methylamine (1 ml, 2M in THF; 2 mmol) was added. After stirring for a further 24 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 the title compound as an off-white solid.
