Versuchsvorschrift

11 Parts of the 5-amino-1-benzyl-4-carbamoyl-1,2,3-triazole obtained are suspended in 50 parts dimethylformamide. At 0°, 15.3 parts phosphorus oxychloride are added dropwise thereto and the mixture is stirred for 15 minutes at room temperature and 15 minutes at 80°. After cooling to 25°, 50 parts 1 N hydrochloric acid are added thereto and the whole is heated to 100° for approximately 5 minutes. On cooling to room temperature the desired product precipitates which is then filtered and dried.
