Reaction Steps

To a mixture of 2-chloro-9-(1-ethyl-propyl)-9H-purine (90 mg, 0.4 mmol) and TsOH (1.6 mL, 0.2 M in 1,4-dioxane) in DMF (0.25 mL) is added 1-[4-(4-amino-phenyl)-piperazin-1-yl]-ethanone (105 mg, 0.5 mmol). The reaction mixture is sealed in a microwave reactor and heated at 140° C. for 30 min. The mixture is diluted with EtOAc and washed with NaHCO3 aqueous solution and brine. The organics are dried over Na2SO4, filtered and concentrated. The crude product is purified by preparative HPLC to give 40 mg of 1-(4-{4-[9-(1-ethyl-propyl)-9H-purin-2-ylamino]-phenyl}-piperazin-1-yl)-ethanone.
