Procedure

20 mL 4 mol/L HCl solution in dioxane was added to 3.35 g 4-(5-methyl-(1,2,4) oxadiazol-3-yl)-piperazine-1-carboxylic acid tert-butyl ester dissolved in 20 mL dioxane was stirred over night. The mixture was diluted with diethylether and the precipitate was filtered and washed with diethylether to give 2.5 g of the desired product.

Workup

  1. filtrationthe precipitate was filtered
  2. washwashed with diethylether
