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, instead of (±)-N-(tert-butoxycarbonyl)-2-(2-phthalimidoethyl)glycine allyl ester, and using 4-(pyridin-4-yl)oxybenzensulfonyl chloride, instead of 4-phenoxybenzenesulfonyl chloride, to afford the desired compound (yield 13%) as a white amorphous solid.
