2-butoxy-2-oxoacetate

反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: 5-(3-Aminophenyl)tetrazole (1.7 g) was added to 12 ml of n-butyloxalate and reacted at a bath temperature of 165° to 175° C. for 1.5 hr while stirring. After cooling, the precipitated crystals were filtered off and recrystallized from acetone-n-hexane, to give 2.3 g (yield: 75%) of 5-(3-n-butyloxalylaminophenyl)tetrazole. reacted at a bath temperature of 165° to 175° C. for 1.5 hr After cooling the precipitated crystals were filtered off recrystallized from acetone-n-hexane
