Procedure

In a microwave vial is added (2-Chloro-5-prop-1-ynyl-pyrimidin-4-yl)-(1-ethyl-propyl)-amine (0.22 g, 0.92 mmol), anhydrous DMF (3 ml), and CuI (53 mg, 0.27 mmol). The reaction is heated at 160° C. for 1 hr by employing microwave. The reaction mixture is diluted with EtOAc, washed with sat. NaHCO3 aqueous solution and water, dried over Na2SO4, and concentrated in vacuo. Purification with column chromatography (SiO2, 1:4 EtOAC/Hexane) gives 43 mg of the desired product.
