Participants

Reaction Steps

tert-Butyl 4-(cyanomethyl)-5-methoxy-7-methyl-1H-indole-1-carboxylate (Example 155-B) (1.2 g, 4.00 mmol) was dissolved in THF (40.0 ml), MeI (0.300 ml, 4.79 mmol) was then added at −78° C. At this point, lithium bis(trimethylsilyl)amide (4.39 ml, 4.39 mmol) was added and the reaction stirred for 10 minutes. The reaction was then quenched at −78° C. with a saturated aq. solution of ammonium chloride, diluted with water and EtOAc and the layers were separated. The organic layer was dried over Na2SO4 and concentrated and purified via FCC (0-50% EtOAc:heptanes) to obtain the title compound. MS (ESI+) m/z 313.5 (M−H).
