Procedure

A mixture of 5.0 g (0.012 mol) of product of Example 19, 1.72 ml (0.012 mol) of triethylamine and 0.75 g of 10% Pd-C in 65 ml of ethanol was hydrogenated at 40° C. under 522 kPa of H2 pressure for 18 hours. The reaction mixture was filtered through celite and concentrated. The residue was taken up in ether, washed with 10% HCl (aq), dried (MgSO4) and concentrated in vacuo to 3.28 g of yellow solid, which was recrystallized in hot hexane to give 2.13 g (47.4%) of product as a light yellow solid, mp 59°-61° C.
