실험 절차

A mixture of N-(4-tert-butylphenyl)-5,6,7,8-tetrahydropyrido[3,4-d]pyrimidin-4-amine (0.066 g, 0.23 mmol), 2-chloro-3-(methylsulfonyl)pyridine (Ponticello et al, J. Org. Chem., 44(17), 1979), (0.088 g, 0.47 mmol) and N,N-diisopropylethlamine (0.041 mL, 0.23 mmol) was heated in a sealed tube via microwave (Emrys Optimizer model, Personal Chemistry) for 30 min at 150° C. The reaction mixture was cooled to r.t. and poured into water (20 mL). The mixture was extracted with ethyl acetate (2×20 mL). The combined organic layers were washed with brine, dried over magnesium sulfate and concentrated to leave an oil which was purified by silica gel chromatography (ethyl acetate/hexane gradient) to give the title compound as a white solid (0.049 g).
