Acetic Acid → HCID 13312558, compound

Participants

Reaction Steps

2.0 g (4.51 mmoles) of Z-Glp-Leu-piperidine are dissolved in 40 ml of methanol, 0.4 g of a 10% palladium-on-carbon catalyst are added to the solution, and hydrogen is bubbled through the mixture for one hour. The catalyst is filtered off, the filtrate is evaporated, and the residue is crystallized from ether. 1.12 g (81%) of Glp-Leu-piperidine are obtained; m.p.: 99°-100° C., Rf5 =0.71, [α]D25 =+30.4° (c=1%, in acetic acid). Analysis for amino acids: Glu=0.95 (1.0), Leu=1.00 (1.0).
