Reaction Steps

The above identified compound was obtained by carrying out the same reaction as in Example 19(1) except that instead of N-(tert-butoxycarbonylmethyl)-{(1R,2R)-1-methyl-2-(4-phenoxyphenyl)-4-phenylbutyl}amine used as the starting material in Example 19(1), N-(benzyloxycarbonylmethyl)-{(1R,2R)-1-methyl-2-(4-phenoxyphenyl)-4-phenylbutyl}amine obtained in Example 52, was used, and instead of 5-tert-butyl 2,2-diethyl (4R,5R)-1,3-dioxolane-2,2,4,5-tetracarboxylate, 5-tert-butyl 2,2-bis{2-(trimethylsilyl)ethyl} (4S,5S)-1,3-dioxolane-2,2,4,5-tetracarboxylate obtained in Example 73, was used.
