Reaction Conditions

Reaction Steps

To a solution of [(R)-5-(3-chloro-4-fluoro-benzenesulfonylamino)-5,6,7,8-tetrahydro-naphthalen-1-yloxy]-acetic acid tert-butyl ester (example 2-2, method D, 2nd step) (400 mg, 0.85 mmol) in acetonitrile (15 mL) was added methyl iodide (182 mg, 1.28 mmol) and potassium carbonate (350 mg, 2.53 mmol). The reaction mixture was stirred at 70° C. for 5 hours, then cooled to room temperature and filtered through a glass funnel. The filtrate was concentrated in vacuo, and the residue was purified by column chromatography (gradient elution, 0-10% methanol in dichloromethane) to afford {(R)-5-[(3-chloro-4-fluoro-benzenesulfonyl)-methyl-amino]-5,6,7,8-tetrahydro-naphthalen-1-yloxy}-acetic acid tert-butyl ester (365 mg, 89%) as a yellow oil. MS cald. for C23H27ClFNO5S 483, obsd. 484 (ESI+) [(M+H)+].
