Procedure
[Step 4] Reactions and treatments were carried out in the same manner as in Step 2 of Example 117, using 89.3 mg of ethyl (2S,4S)-1-acetyl-4-hydroxyl-2-methyl-1,2,3,4-tetrahydroquinoline-6-carboxylate instead of ethyl (2S,4R)-1-acetyl-4-hydroxyl-2-methyl-1,2,3,4-tetrahydroquinoline-6-carboxylate, and 4-nitrophenol was used instead of benzoic acid. Thus, 73.6 mg (57.4%) of ethyl (2S,4R)-1-acetyl-2-methyl-4-(4-nitrophenoxy)-1,2,3,4-tetrahydroquinoline-6-carboxylate was obtained as a white solid.
