Participants

Reaction Steps

A suspension of 2.70 g (6.10 mmol) of the compound obtained in Step 2 and 1 g of Pd(OH)2 in 120 ml of EtOH is hydrogenated under one atmosphere for 12 hours. After filtering off the catalyst, the solvent is evaporated off in vacuo. The residue obtained is chromatographed on SiO2, eluting with a solution of cyclohexane/EtOAc=40/60, to yield the title compound in the form of 2 diastereoisomers.
