Versuchsvorschrift
To a slurry of (5-amino-1H-[1,2,4]triazol-3-yl)-methanol (28.5 g, 150 mmol, from step 6 of example A(1)) in acetic acid was added chloromalonaldehyde (16 g, 150 mmol). The mixture was heated to 80° C. for 4 hours. Upon cooling of the reaction, the product crystallized out as a white solid (25.5 g, 92%). 1H NMR (300 MHz, DMSO-d6): δ 4.67 (s, 2 H), 5.62 (s, 1 H), 8.94 (d, J=2.45 Hz, 1 H), 9.81 (d, J=2.45 Hz, 1 H).
