Participants

Reaction Steps

A 300 mL Fisher Porter vessel equipped with magnetic stirring bar was charged with 7.2 g benzyl 3-(4-tert-butoxycarbonylpiperizin-1-ylsulfonyl)-2(R)-methylpropionate, 600 mg 10% Pd—C, and 100 mL MeOH. The reaction vessel was charged with 50 psi H2 and stirred for 2 hours at room temperature. The reaction mixture was filtered thru Celite and concentrated in vacuo to yield 5.25 g (93%) white solid. The free acid was used without further purification.
