HCID 145143744-[1-(1-Imidazolyl)-butyl]-benzoic acid methyl ester

実験手順

1.0 of 4-[1-(1-imidazolyl)-butyl]-benzoic acid, hydrochloride (of example 2) is dissolved in 30 ml of methanol, hydrochloric-acid gas is introduced for 10 minutes, refluxed for 30 minutes and concentrated by evaporation. The residue is distilled on a bulb tube, boiling point 190° C./0.03 mbar. 0.55 g of 4-[1-(1-imidazolyl)-butyl]-benzoic acid methyl ester is obtained.

後処理

  1. temperaturerefluxed for 30 minutes
  2. concentrationconcentrated by evaporation
  3. distillationThe residue is distilled on a bulb tube
