Procedure

The unsaturated acid (3.2 g, from Step D) in glacial acetic acid (200 ml) and platinum oxide (1.0 g) was hydrogenated at 60° C. under 40 psi for 24 hours. The mixture was filtered through a pad of celite, and the filtrate concentrated to dryness. The residue was recrystallized from 5% MeOH in methylene chloride to yield the title acid.
