実験手順

7-Benzyl-4-chloro-5,6,7,8-tetrahydropyrido[3,4-d]pyrimidine (12.0 g, 46.3 mmol) was dissolved in 20 mL of anhydrous acetonitrile and 4-(trifluoromethyl)aniline was added (7.0 mL, 55.6 mmol), followed by 47% HI/H2O (2.0 L) and sodium iodide (10.3 g, 69.5 mmol). The mixture was heated at refluxed overnight and solvents were removed under vacuum. The residue was dissolved in ethyl acetate and washed with sat. NaHCO3 and brine. The organic layer was dried over Na2SO4, filtered and evaporated to a yellow solid which was purified by silica gel flash chromatography using a gradient of ethyl acetate:hexane (0-100%) to give the desired compound as a brown oil (15 g).
