Versuchsvorschrift
A 100 mL Fisher/Porter vessel was charged with benzyl 3-[(4-methylpiperizin-1-yl)sulfonyl]-2(R)-methylpropionate in 15 mL MeOH with a catalytic amount of 10% Pd—C. Hydrogenation at 50 psi for 48 hours afforded, after filtration through Celite and concentration in vacuo to yield 3-[(4-methylpiperizin-1-yl)sulfonyl]-2(R)-methylpropionic acid as a hygroscopic foam suitable for use without further purification.
