HCID 86660763, compound → (2S,4R)-1-acetyl-2-methyl-4-[2,2,2-trifluoro-N-(4-morpholinophenyl)acetamido]-1,2,3,4-tetrahydroquinoline-6-carboxylic acid

Participants

Reaction Steps

[Step 3] Reactions and treatments were carried out in the same manner as in Step 5 of Example 117, using 111.1 mg of (2S,4R)-1-acetyl-2-methyl-4-[2,2,2-trifluoro-N-(4-morpholinophenyl)acetamido]-1,2,3,4-tetrahydroquinoline-6-carboxylic acid benzyl ester instead of ethyl (2S,4R)-1-acetyl-2-methyl-4-(4-nitrophenoxy)-1,2,3,4-tetrahydroquinoline-6-carboxylate, and using ethanol instead of methanol. Thus, 83.5 mg (88.3%) of (2S,4R)-1-acetyl-2-methyl-4-[2,2,2-trifluoro-N-(4-morpholinophenyl)acetamido]-1,2,3,4-tetrahydroquinoline-6-carboxylic acid was obtained as a pale yellow amorphous substance.
