| titleOfInvention | Novel preparation of 5-aryl-1h-tetrazole derivative and its intermediate |
| abstract | PURPOSE: To obtain the titled substance useful as an intermediate for drugs inexpensively, by reacting a reaction product of a toluene derivative and N- bromosuccinimide, etc. with an alkali metal azide, etc. to give diamidomethylbenzene, decomposing it thermally. n CONSTITUTION: A compound shown by the formula I (R 1 and R 2 are H, halogen, nitro, or alkoxy) is reacted with N-bromo or chlorosuccinimide in an inert solvent (e.g., benzene, CCl 4 ) to give a compound shown by the formula II (X 1 and X 2 are Br, or Cl), which is reacted with an alkaline (earth) metal azide or ammonium azide in an inert solvent (e.g., DMF, DMSO, acetone) to give a compound shown by the formula III, which is thermally decomposed in a solvent such as DMF, acetic acid, toluene, etc. at 50W200°C in an inert gas atmosphere, to give a compound shown by the formula IV. n EFFECT: This process is economic because an inexpensive compound shown by the formula I is used as a starting raw material. n COPYRIGHT: (C)1984,JPO&Japio |
