Reaction Steps

A solution of N-t-butoxycarbonyl-2-(3-methyl-2-butenyl)-sarcosine methyl ester (22.1 g, 81.44 mmol) in 400 ml of methanol under nitrogen was cooled to 0° C. and 1.5 g of 10% Pd/C was added. The mixture was placed into a Parr Apparatus and hydrogenated at 50 psi for 6 hours. The catalyst was removed on a pad of CELITE® and the filtrate was concentrated in vacuo to afford 22.04 g (99%) of N-t-butoxycarbonyl-2-(3-methylbutyl)-sarcosine methyl ester as an oil.
