Versuchsvorschrift

A solution of (R)-2-[2-(tert-butoxy)-2-oxoethyl]-5-phenylpentanoic acid (2.2 g, 7.5 mmol) and 5%Rh/C (0.22 g) in methanol (220 ml) was stirred at room temperature, under hydrogen (150 p.s.i.) for 24 hours and then filtered through celite. The filtrate was concentrated in vacuo to leave the title compound as an oil (2.0 g).
