实验步骤: To a solution of 0.086 g (0.202 mmol) N-[(S)-(4-bromophenyl)(1-methyl-1H-1,2,3-triazol-4-yl)methyl]-2-(4-cyclopropylphenyl)acetamide in 1.0 ml THF was added 0.021 g (0.243 mmol) n-propylboronic acid, 0.017 g (0.020 mmol) PdCl2(dppf)-CH2Cl2 adduct, 0.084 g (0.607 mmol) solid potassium carbonate, and 0.117 g (0.607 mmol) Silver(I) oxide. The reaction mixture was irradiated in the microwave at 150° C. for 30 mins. The resulting solution was diluted with CH2Cl2, washed twice with water, dried over sodium sulfate, filtered, and concentrated in vacuo.
