実験手順: Compound 2B was prepared following the procedure used to prepare compound 1B of Example 1, except that 4-amino-2-methylphenol (2A) was used instead of compound 1A. LCMS-ESI+ (m/z): 174.2 (M+H)+.

実験手順: Potassium carbonate (5.04 g, 36.5 mmol) was added at room temperature to a solution of 4-amino-o-cresol (3.00 g, 24.4 mmol) and ethyl bromoacetate (2.70 mL, 24.4 mmol) in DMF (30 mL). The resulting solution was stirred at room temperature for 1.5 hours. Water was added to the reaction mixture, and extracted with ethyl acetate. The ethyl acetate layer was washed with brine. The ethyl acetate layer was dried over anhydrous sodium sulfate, and evaporated. The residue was purified by silica gel column chromatography (n-hexane:ethyl acetate=3:1), to thereby yield 5.10 g of the title compound. extracted with ethyl acetate The ethyl acetate layer was washed with brine The ethyl acetate layer was dried over anhydrous sodium sulfate evaporated The residue was purified by silica gel column chromatography (n-hexane:ethyl acetate=3:1)
