Description
13C-NMR (CDCl3-TMS, δ ppm): 134.67, 134.04, 128.96, 128.93, 127.86, 123.39, 53.75;
質量 (m/z): 160.2[M+1]
イソプロピルアルコール(500リットル)中の1-ベンジル-1H-[1,2,3]トリアゾール(125kg、実施例1で得られた)を、20〜25kgの圧力下、110℃で、10〜12時間の間、3.75kgの5%Pd−Cを用いて水素化した。反応の最終段階で、ベンジルトリアゾール含有量は1.66%であり、トリアゾール含有量は98.34%であった。反応生成物を室温まで冷却し、ハイフローベッドを通してPd−Cを濾過し、このベッドをイソプロパノール(100リットル)で洗浄した。真空下で蒸留して溶媒を完全に取り除き、粗生成物である1H-[1,2,3]トリアゾール(78kg)を得た。こうして得られた粗生成物を、高真空蒸留(2〜5mm)により精製し、標題の化合物(38〜42kg)を蒸気温度(80〜83℃)で回収した。
13C-NMR (CDCl3, δ ppm): 129.47
1. 本方法は、非常に単純であり、容易に入手可能な出発原料から開始されるので、経済的且つ工業的に実行可能なものである。
2. 酢酸ビニルは、他のアセチレン同等物に比べて取り扱いが容易であり、実質的により割安な出発原料である。
3. 本方法は、アセチレンガスを扱う工程を含まないので、プラントスケールにおいて、制御するのに特別な注意が必要ない。
