実験手順

The compound of Example 2 (1.8 g,) was dissolved in ethanol then 0.2 g 5% Pd/C was added to the solution. The mixture was treated with hydrogen gas at 45 psi. Upon completion of the reaction, the solution was filtered through Celite, and the filtrate concentrated under vacuum. The named product slowly crystallized upon standing (m.p. 93° C.-95° C.).
