Reaction Steps

A mixture of material from Example 22A and 10% Pd—C (500 mg) in methanol (250 mL) was stirred under an atmosphere of hydrogen at ambient temperature for 4 hours. The mixture was filtered through celite and the filtrate concentrated under reduced pressure to provide the titled compound.
