Reaction Steps

In a similar manner to the procedures described in Example 1(2)-a and b, reactions were carried out using (±)-N-(tert-butoxycarbonyl)-2-(2-phthalimidoethyl)glycine benzyl ester, the product of Example 19(1), instead of (±)-N-(tert-butoxycarbonyl)-2-(2-phthalimidoethyl)glycine allyl ester, and using 4-methoxybenzenesulfonyl chloride, instead of 4-phenoxybenzenesulfonyl chloride, to afford the desired compound (yield 61%) as a white powder.
