3-Methoxypropylamine → HCID 131720195, compound

Participants

Reaction Steps

In substantially the same manner as Working Example 2, 3-methoxypropylamine (6.1 ml, Wako Pure Chemical Industries, Ltd.) was condensed with Boc-L-leucine monohydrate (5.00 g, manufactured by Peptide Institute, Inc.) to afford N-(Boc-L-leucyl)methoxypropylamine (17.5 g) as a colorless waxy product (yield 89%). The Boc group was deprotected by using TFA, and 1.21 g of the resultant compound was condensed, in substantially the same manner as Working Example 2, with (2S,3S)-ethyl hydrogen N-Z-aziridine-2,3-dicarboxylate (Compound 1, 1.93 g) to afford the above-titled compound (Compound 20; 2.55 g) as a white crystalline product (yield 89%).
