The reaction mixture was refluxed for additional 60 min, cooled to room temperature and filtered through Celite. The filtrate was concentrated to dryness to give 4-tert-butyl-3-methoxyaniline (C-2) (52 mg, 72%) that was used without further purification. HPLC ret. time 2.29 min, 10-99% CH3CN, 5 min run; ESI-MS 180.0 m/z (MH+).
