실험 절차

4-amino-3-ethoxy-benzamide (0.045 g, 0.25 mmol), methyl 4-chloro-5-methyl-thieno[2,3-d]pyrimidine-6-carboxylate (0.061 g, 0.25 mmol, Fluorochem Ltd.) and para-toluene sulfonic acid (0.005 g, 0.025 mmol) were heated at reflux in anhydrous 1,4-dioxane (1.5 mL) for 16 hours. The solution was cooled to ambient temperature, ammonium hydroxide/water (1:4, 5 mL) added and the precipitate collected and washed successively with water and diethyl ether. The title compound was obtained as a yellow solid (0.057 g, 59%) after recrystallisation from MeOH.
