Reaction Conditions

Reaction Steps

To a solution of 0.032 g (0.12 mmol, 1.0 eq.) of N4-cyclopropyl-N2-(2-(thiophen-2-yl)ethyl)pyrimidine-2,4,5-triamine (I-3) in 5 mL of DMA was added 0.05 mL (0.38 mmol, 3.2 eq.) of 4-pyridinecarboxaldehyde. The mixture was stirred at 140° C. for 16 h and the solvent was removed in vacuo. The residue was purified by flash chromatography (EtOAc) to afford 0.015 g (0.04 mmol, 35%) of 9-cyclopropyl-8-(pyridin-4-yl)-N-(2-(thiophen-2-yl)ethyl)-9H-purin-2-amine (I-4) as a yellow solid.
