Reaction Steps

To a solution of (+/−)-[8-bromo-9-[(4-chlorophenyl)sulfanyl]-6-fluoro-2,3-dihydro-1H-pyrrolo[1,2-a]indol-1-yl]acetic acid (Example 7, 100 mg, 0.22 mmol) in THF (4 mL) at −78° C. was added 3M MeMgBr (0.26 mmol) followed by the addition of 1.3M sec-BuLi (0.31 mmol). The reaction mixture was stirred at −78° C. for 5 minutes and an excess of acetaldehyde was added. The reaction was stirred at −78° C. for 30 minutes and quenched with saturated aqueous NH4Cl. The phases were separated and the aqueous layer was extracted with EtOAc. The combined organic layers were dried over Na2SO4 and concentrated. The residue was purified by silica gel chromatography eluted with EtOAc/Hexanes/AcOH (20:30:1) to provide 65 mg of the title compound as a white solid.
