Procedure
To a 4 mL vial were added 3,5-dimethyl-benzene-1,2-diamine.2HCl (69 mg, 0.33 mmol), 4-methyl-2-[3-(1-methyl-piperidin-4-yl)-propylamino]-pyrimidine-5-carbaldehyde (92 mg, 0.33 mmol), 2,3-dichloro-5,6-dicyano-p-benzoquinone (75 mg, 0.33 mmol), and DMF (2 mL). After addition of triethylamine (0.09 mL, 0.66 mmol), the resultant mixture was stirred for 5 hours at room temperature. The resultant mixture was then diluted with 1N NaOH (7.5 mL) and dichloromethane (7.5 mL). The organic layer was concentrated and purified by flash chromatography to yield the title compound. MS: [M=H]+=393
