methyl N-{[4-({[(benzyloxy)carbonyl]amino}methyl)cyclohexyl]carbonyl}-L-norleucinate → methyl N-{[4-(aminomethyl)cyclohexyl]carbonyl}-L-norleucinate

Participants

Reaction Steps

A mixture of methyl N-{[4-({[(benzyloxy)carbonyl]amino}methyl)cyclohexyl]carbonyl}-L-norleucinate (830 mg, 1.98 mmol), 10% palladium on C (0.056 g) in methanol (10 mL) was stirred under an atmosphere of hydrogen for 4 hours. The mixture was filtered through diatomaceous earth and the filter cake washed with methanol (2×15 mL). The combined methanol was concentrated under reduced pressure to provide the titled compound as a colorless solid.
