実験手順
In analogy with Example 44d), 1.315 g of 5(S)-[1(S)-(Boc-amino)-2-phenylethyl]-3(R)-[(3-methoxyphenyl)methyl]dihydrofuran-2-(3H)-one in 49.9 ml of dimethoxyethane and 25.16 ml of water are hydrolysed with 12.36 ml of a 1M lithium hydroxide solution to give the title compound, which is directly subjected to further processing. TLC Rf (C)=0.09. FAB-MS (M+H)+ =444.
