Reaction Steps

By carrying out the reaction as described in Example 107, Step B, except that the N-(t-butoxycarbonylmethyl)-[(5,6-dichloro-9a-ethyl-3-oxo-1,2,9,9a-tetrahydro-3H-fluoren-7-yl)oxy]acetamide is replaced by an equimolar amount of N-[2-(t-butoxycarbonyl)ethyl]-[(5,6-dichloro-9a-ethyl-3-oxo-1,2,9,9a-tetrahydro-3H-fluoren-7-yl)oxy]acetamide. There is obtained N-(2-carboxyethyl)-[(5,6-dichloro-9a-ethyl-3-oxo-1,2,9,9a-tetrahydro-3H-fluoren-7-yl)oxy]acetamide.
