Procedure

A solution of 2.46 g (4.64 mmol) of N-(2-t-butyl-5-carbamoylphenyl)-3-(4-benzyloxy-2-methoxyphenyl)octanamide (prepared as described in Example 123) in 100 ml of ethanol was vigorously stirred at 40° C. under a stream of hydrogen in the presence of 10% palladium-on-charcoal for 1.5 hours. At the end of this time, the reaction mixture was filtered using a Celite (trade mark) filter aid to remove the catalyst, and the filtrate was concentrated to dryness by evaporation under reduced pressure. The residue was purified by column chromatography through 100 g of silica gel using a 49:1 by volume mixture of ethyl acetate and methanol as the eluent, to give a crude product containing the title compound. This product was further purified by column chromatography through silica gel under the same conditions as above to give 1.62 g (yield 79%) of the title compound as a foam-like substance.
