Reaction Steps

The title compound of Example 93 (1.9 g) was dissolved in 10 ml of acetic acid in a bottle. To the system was added 1.9 g of 5% platinum/carbon (60% water), and the mixture was shaken under hydrogen (40 p.s.i.) for 4 hours. The mixture was diluted with ethanol, filtered through diatomaceous earth (Celite (trademark)) and the filtrate was concentrated. Saturated aqueous sodium bicarbonate was added to the residue until the pH of the mixture was ca. 8, and the mixture was extracted with chloroform. The chloroform extracts were dried (sodium sulfate) and concentrated to obtain 1.6 g of the title compound as an oil.
