1-Naphthalenemethanamine → HCID 22876889, compound

Participants

Reaction Steps

In substantially the same manner as Working Example 2, 1-naphthalenemethylamine (4.32 g) was condensed with Boc-L-phenylalanine (6.63 g) to give N-(Boc-L-phenylalanyl)-1-naphthalenemethylamine (7.92 g) (yield 91%). The Boc group of the product was deprotected in substantially the same manner as Working Example 91 to give N-(L-phenylalanyl)-1-naphthalenemethylamine hydrochloride (4.24 g) (yield 64%). The compound thus obtained (0.75 g) was condensed, in substantially the same manner as Working Example 8, with monoethyl ester of (2S,3S)-N-benzylaziridine-2,3-dicarboxylic acid (0.50 g) obtained in Working Example 95 to give the above-titled compound (Compound 99; 0.79 g) as white crystals (yield 74%).
