実験手順
To a 5 mL CEM microwave reaction vessel, was charged benzotriazole HCl salt (0.5 g, 3.2 mmol) and cyanamide (0.16 g, 3.9 mmol). The vessel was sealed and heated at 80° C. for 1 minute under microwave irradiation (CEM Discovery™). After this time, TLC analysis showed no starting material remaining so the mixture was diluted with ether. The precipitate was collected by filtration and washed with ether and dried under vacuum to afford the titled product as a white solid (0.45 g, 71% yield). 1H NMR (400 MHz, d6-DMSO) δ: 10.14 (4H, s), 8.31 (1H, m), 8.05 (1H, m), 7.90 (1H, m), 7.67 ('H, m). MS m/z: 162.13 [M+H]+.
