Reaction Steps

Eaton's reagent (100 mL, 630 mmol, 6.6 equiv.) was added to 2-[(3-fluorophenyl)amino]cyclopentanecarboxylic acid 6A (21.3 g, 95 mmol, 1 equiv). The mixture was heated to 70° C. and stirred for one hour. The reaction mixture was then cooled to 23° C. and quenched with the addition of wet ice. The mixture was then neutralized to pH=10 with the portionwise addition of solid sodium hydroxide pellets. The reaction mixture was then partitioned between ethyl acetate and water. The organic layer was washed with saturated aqueous sodium chloride solution, and the washed solution was dried over sodium sulfate. The dried solution was filtered, and the filtrate was concentrated. The filtrate was purified by flash-column chromatography (hexanes, grading to 50% ethyl acetate-hexanes) to afford 6B. [M+H]+: 206.2.
