A solution of methyl 3-amino-4-methylbenzoate (commercially available) (1.609 g, 9.74 mmol), TBD (2,3,4,6,7,8-hexahydro-1H-pyrimido[1,2-a]pyrimidine) (0.678 g, 4.87 mmol) and (2-(4-methylpiperazin-1-yl)phenyl)methanamine (commercially available) (2 g, 9.74 mmol) in toluene (30 ml) was heated at reflux overnight. The reaction mixture was diluted with EtOAc and washed with sat.NaHCO3 and water. The organic portion was separated, dried (MgSO4) and concentrated in vacuo. The product was purified by chromagraphy on silica eluting with a gradient of 0-20% 2M NH3 in MeOH/DCM to afford the title compound;
