Sodium hydride → 2-[6-Chloro-3-(2,2,2-trifluoro-acetyl)-indol-1-yl]-N-methyl-acetamide

Participants

Reaction Steps

To a stirred solution of 1-(6-chloro-1H-indol-3-yl)-2,2,2-trifluoro-ethanone (described previously in U.S. 2004067939) in DMF were added 2.1 eq. NaH (60% in oil). The mixture was stirred at RT for 30 min. and then the (commercially available) 2-chloro-N-methyl-acetamide (1.1 eq.) was added. The mixture was stirred an additional 14 hours at 60° C. and then poured onto water and extracted with ethyl acetate. The combined organic phases were dried over Na2SO4 and concentrated in vacuo. Purification by preparative HPLC gave the title compound.
