Procedure

To a solution of tert-butyl 4-((tert-butylsulfinyl)imino)(5-cyanobenzo[d]oxazol-2-yl)methyl)-5-methoxy-7-methyl-1H-indole-1-carboxylate (Example 130-A) (0.56 g, 1.047 mmol) in THF (10.47 mL), MeMgCl (3M in THF, 1.047 mL, 3.14 mmol) was added at 0° C. After 10 minutes the mixture was diluted with sat. aq. NH4Cl and EtOAc. The aqueous layer was extracted with EtOAc, and the organic extract was dried over MgSO4, filtered and concentrated. The product was purified by flash chromatography (0-100% EtOAc:Heptanes) to provide the title compound. MS (ESI+) m/z 551.2 (M+H).
