실험 절차

The methyl ester precursor of (S)-4-[cis-2,6-dimethyl-4-(4-trifluoromethoxy-phenyl)-piperazine-1-sulfonyl]-indan-2-carboxylic acid tosylate (hereinafter optionally referred to as “Compound 1 tosylate”) was used for this experiment instead of Compound 1 tosylate due to the unsuitability of the Compound 1 tosylate crystals for X-ray structure determination. Compound 1 tosylate methyl ester was prepared via an esterification of Compound 1 tosylate followed by recrystallization from isopropanol. Other experiments have established that the stereochemistry is retained in converting the methyl ester to Compound 1 tosylate.
