To a solution of (3-amino-1H-1,2,4-triazol-5-yl)methanol (16.6 g, 87.6 mmol) in acetic cid was added 3-ethoxymethacrolein (10.0 g, 87.6 mmol), and the mixture was heated to 80° C. for 4 hours. Upon cooling of the reaction, the product crystallized out of solution. The collected product was a white solid (14.0 g, 92%). 1H NMR (300 MHz, DMSO-D6) δ: 2.38 (m, 3 H) 4.63 (m, 2 H) 5.52 (m, 1 H) 8.75 (m, 1 H) 9.21 (m, 1 H). MS (APCI, M+H+): 163.1, 165.1.
