実験手順
To a cooled (ice bath), stirred solution of Boc-Gly-Gly-Ala-Gly-OMe (2.5 g, 6.7 mmoles, described in Example 4) in methanol (50 ml) is added hydrazine hydrate (2.5 ml). The solution is stirred at 0° C for 3 hr and at room temperature overnight. The precipitate is separated by filtration, washed with methanol and dried to yield the title compound; amino acid analysis: Gly 3, Ala 0.99.
