Procedimiento

Substantially monodispersed benzyl ether 3 (1.03 g, 2.0 mmol) was dissolved in 25 ml ethanol. To this solution was added 270 mg 10% Pd/C, and the mixture was placed under a hydrogen atmosphere and stirred for four hours, at which time TLC showed the complete disappearance of the starting material. The reaction mixture was filtered through Celite 545 to remove the catalyst, and the filtrate was concentrated in vacuo to yield the monodispersed compound 4 as a clear oil (0.67 g, 79%). FAB MS: m/e 425 (M+H), 447 (M+Na).
