Procedure

Compound (c) (1.47 g; 3.38 mmole) was hydrogenated for 3 hours at atmospheric pressure in ethyl acetate (50 ml) using Pd/C (0.74 g, 5%) as a catalyst. The reaction mixture was filtered through celite, dried (magnesium sulfate) and the solvent was evaporated in vacuo to give 1.44 g (yield 98%) of the desired product.

Workup

  1. filtrationThe reaction mixture was filtered through celite
  2. dry with materialdried (magnesium sulfate)
  3. customthe solvent was evaporated in vacuo
