Procedure

6-[4-(2-Benzyloxyacetylamino)-phenoxy]-hexanoic acid methyl ester 53 (1 grams, 2.6 mmol) was dissolved in methanol (10 ml) in a pressure vessel. Palladium on carbon (5%, 250 mg) was added and the mixture stirred under a hydrogen atmosphere (2 kg) for 5 hrs. Catalyst was removed by filtration and methanol distilled off. Crude 54 was recrystallised in chloroform:hexane (1:6) to get pure 54 (0.5 g, 65.3%) as a white powder with an m.p. between 91.5-94° C.
