4-Chloro-2-(5-methoxymethyl-2H-[1,2,4]triazol-3-yl)-phenylamine (60.6 g, 239 mmol) was dissolved in acetic acid (1.2 L) and chloroacetic chloride (40.4 mL, 508 mmol) was added dropwise at 14-16° C. over a period of 30 min. The resulting reaction mixture was stirred for 22 h at ambient temperature. After addition of water (600 mL) and stirring for another 90 min, the solid was filtered off and washed with water (600 mL). Drying in vacuo afforded the title compound (66.2 g, 83%) which was obtained as a yellow solid. MS: m/e=314.9 [M+H]+.
