실험 절차

4-Fluoro-2-(tetrahydro-2H-pyran-4-yloxy)aniline (0.057 g, 0.27 mmol), 4,6-dichloro-5-methylthieno[2,3-d]pyrimidine (0.06 g, 0.27 mmol, CA56844-14-5) and para-toluene sulfonic acid (0.005 g, 0.03 mmol) were heated at 90° C. in anhydrous 1,4-dioxane (1.5 mL) for 18 hours. The solution was cooled to ambient temperature, diluted with water (2 mL) and adjusted to pH 10 (4:1 water/ammonium hydroxide solution). The precipitate was collected, washed with water and diethyl ether to yield the title compound as yellow solid (0.012 g, 11%).
