Reaction Steps

1.77 g (3.1 mmol) of the diester obtained in Example 44, in solution in 50 ml of dioxane, are hydrogenated in the presence of 530 mg of palladium on carbon (10%) at 50° C., under a hydrogen pressure of 7 bar. After the same treatment as in Example 5 followed by a recrystallization from ethyl acetate, 1.13 g (83%) of the expected product are isolated, which product melts at 260° C.
