Under argon, 319 mg (0.30 mmol, 10% pure) of palladium on activated carbon and 9.1 ml (90.0 mmol) of cyclohexene were added to 1.0 g (3.0 mmol) of rac-benzyl (7,7,7-trifluoro-2-hydroxy-2-methylheptan-3-yl)carbamate Example 101A in ethanol (21 ml), and the reaction mixture was stirred at reflux overnight. The mixture was filtered through a Millipore® filter and the filter cake was washed with ethanol. 3 ml (6.0 mmol) of 2 N hydrochloric acid in diethyl ether were added to the filtrate and the mixture was concentrated and dried under high vacuum. This gave 785 mg (111% of theory) of the target compound. The product was used without further purification for the next reaction.
