Reaction Steps

To a solution of ethyl 4-chloro-5-cyano-1-(2,2,2-trifluoroethyl)-1H-indole-2-carboxylate (0.02 g, 0.06 mmol) in 1:1 THF/MeOH (4 mL) was added 1N NaOH (1 mL) and the mixture was heated at 70° C. for 1.25 h. Upon cooling, the mixture was partially concentrated under vacuo. The residue was partitioned between EtOAc and 0.2N HCl. The organic phase was washed with sat'd brine. The combined aqueous phases were reextracted twice with EtOAc. The organic phases were combined and washed with sat'd brine, dried (Na2SO4) and concentrated in vacuo to afford the title compound (0.017 g, 94% yield): MS (ES) m/z 301 (M−1).
