Procedure
A mixture of 2,4-Dichloro-5-phenyl-thieno[2,3-d]pyrimidine (1.77 g, 6.3 mmol), 2-aminomethylpyridine (Aldrich, 782 μl, 7.6 mmol), and triethylamine (VWR, 1.06 ml, 7.63 mmol) were refluxed in ethanol (30 ml) for 3 hrs. On cooling, the reaction was poured into water (300 ml) and stirred for 1 hr. The resulting precipitate was filtered, washed with water (2×30 ml) and dried under vacuum at 40° C. to give (2-Chloro-5-phenyl-thieno[2,3-d]pyrimidin-4-yl)-pyridin-2-ylmethyl-amine as a pale-yellow solid. Yield=(1.55 g, 70%).
