실험 절차

3-Amino-2-methylphenol (2.0 g; 16 mmol) and di-t-butylcarbonate were dissolved in THF (20 mL) and refluxed overnight. Evaporation of the solvent followed by flash chromatography (SiO2; EtOAc 5-30% in isohexane) afforded 2.48 g (69%) of the sub-title compound.

후처리

  1. temperaturerefluxed overnight
