1-(迭氮基甲基)-2-氟-苯

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: The starting material may be prepared as follows: A solution of 50 g (0.33 mole) of o-fluorobenzyl azide, 23.1 g (0.33 mole) of propinecarboxylic acid and 400 ml of toluene is stirred for 24 hours at 70° C. After the reaction mixture has cooled to room temperature, the precipitated product is filtered with suction and washed first with toluene and then with diethyl ether, affording 1-(o-fluorobenzyl)-1H-1,2,3-triazole-4-carboxylic acid with a melting point of 151° C. (dec.). The starting material may be prepared the precipitated product is filtered with suction washed first with toluene

反应条件: temp:90.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: The starting material may also be prepared as follows: A solution of 40 g (0.282 mole) of dimethyl acetylenedicarboxylate in 500 ml of toluene is added dropwise to a solution of 41.5 g (0.255 mole) of o-fluorobenzyl azide in 50 ml of toluene, which solution has been heated to 90° C. After a further 5 hours at 90° C., the toluene is stripped off, the reaction mixture is cooled and the crystalline product is filtered with suction. Recrystallisation from a 1:1 mixture of diethyl ether/petroleum ether yields dimethyl 1-(o-fluorobenzyl)-1H-1,2,3-triazole-4,5-dicarboxylate with a melting point of 49°-51° C.
