Procedure

475 mg (1.65 mmol) of the compound from Example 36A are dissolved in 48 ml of THF. 50 mg (0.05 mmol) of palladium on carbon are then added, and the mixture is hydrogenated at RT in a hydrogen atmosphere under atmospheric pressure. The mixture is then filtered, the filter cake is washed three times with THF and the filtrate is freed from the solvent. The reaction product is reacted further without further purification.

Workup

  1. filtrationThe mixture is then filtered
  2. washthe filter cake is washed three times with THF
  3. customThe reaction product is reacted further without further purification
