Versuchsvorschrift

The title compound of Example 32 (10 g, 34 mmole) dissolved in 120 ml of THF and 100 ml of MeOH was reduced in a standard Parr hydrogenation apparatus using 1 g of 5% Pd/C as catalyst. The reaction was run at room temperature under a pressure of 5 psi for 24 hours. The residue after removing all solvent under reduced pressure was chromotographed to yield the pale yellow crystalline product which was recrystallized from Skelly B. The melting point was 92°-93.5° C.
