Reaction Steps

Following general method A-18, 7-Bromo-5-fluoro-3-methyl-1H-indole (1.60 g, 7.02 mmol) was reacted with 2,4-dichlorophenol (1.72 g, 10.5 mmol), CuI (134 mg, 0.702 mmol), N,N-dimethylglycine hydrochloride (293 mg, 2.10 mmol), and Cs2CO3 (4.57 g, 14.0 mmol) in anhydrous dioxane (14 mL). The crude product was purified by silica gel column chromatography utilizing a solvent system of 5% EtOAc/Hexanes to yield 746 mg of I-198B as a yellow oil (34%). 1H NMR (400 MHz, CDCl3)
