실험 절차

A solution of 5-bromo-3-(5-phenyl-1,3,4-oxadiazol-2-yl)pyrazin-2-amine (100 mg, 0.31 mmol), 2-ethanamidophenylboronic acid (56.25 mg, 0.31 mmol), tetrakis(triphenylphosphine)palladium (18.17 mg, 0.015 mmol) and Na2CO3 (471 μL, 2M aqueous solution) were added to a 10 mL microwave vial. Dioxane (3 mL) was then added and the vial sealed. The reaction mixture was heated in the microwave at 150° C. for 30 min. After this time methanol was added and the reaction mixture filtered. The solid was then washed with water (5 mL) and MeOH (5 mL) and dried under vacuum to give the product (31.0 mg, 28% yield); 1H NMR (400.0 MHz, DMSO) d 2.04 (s, 3H), 7.26 (t, 1H), 7.44-7.40 (m, 1H), 7.69-7.67 (m, 4H), 7.80 (d, 2H), 8.15-8.13 (m, 3H), 8.73 (s, 1H) and 10.76 (s, 1H) ppm; MS (ES+) 373.0
