Reaction Steps
The crude N-[4-cyano-2-methyl-3-(trifluoromethyl)phenyl]-2,2-dimethylpropanamide from Example 191B was dissolved in EtOH (5 mL) and conc. HCl (5 mL). The resulting mixture was heated to 70° C. for 20 min. The cooled reaction's pH was adjusted to ca. 8 with 6 N NaOH. EtOAc (20 mL) was added and the isolated organic portion was dried (Na2SO4), filtered, and concentrated to afford the title compound: MS (ES) m/z 201 (M+1).
