Procedure: A solution of chloroacetyl chloride (0.71 mL, 8.94 mmol) in THF (5 mL) was added dropwise to a solution/suspension of 2-amino-6-methylphenol (1 g, 8.13 mmol) and triethylamine (1.24 mL, 8.94 mmol) in THF (50 mL) which had been pre-cooled in an ice-water bath. After stirring for 5 minutes a further portion of triethylamine (1.24 mL, 8.94 mmol) was added. The mixture was stirred and warmed to r. t. After 24 h the reaction was allowed to stand overnight. The mixture was concentrated in vacuo and the residue was partitioned between water (100 mL) and EtOAc (50 mL). Brine (20 mL) was added to the aqueous phase, and this was further extracted with EtOAc (50 mL). The combined organic fractions were dried (MgSO4), concentrated in vacuo, and purified by column chromatography (SiO2, 20-100% EtOAc/heptane) to give an orange-brown solid (1.04 g), which was dissolved in THF (10 mL) and triethylamine (2 mL), and the mixture left to stand for 3 days. The mixture was concentrated in vacuo and purified by column chromatography (SiO2, 10-50% EtOAc/heptane) to give a cream solid (0.6 g). This was dissolved in DCM (40 mL), and the solution was washed with aqueous NaOH (2M, 10 mL). The organic fraction was dried (MgSO4) and concentrated in vacuo to give the title compound (0.29 g, 22%) as a beige solid. LCMS (ES+) 164 (M+H)+, RT 2.61 minutes (Method 1). had been pre-cooled in an ice-water bath was added warmed to r to stand overnight The mixture was concentrated in vacuo the residue was partitioned between water (100 mL) and EtOAc (50 mL) Brine (20 mL) was added to the aqueous phase this was further extracted with EtOAc (50 mL) The combined organic fractions were dried (MgSO4) concentrated in vacuo purified by column chromatography (SiO2, 20-100% EtOAc/heptane)

Procedure: An ambient solution of 2-amino-6-methylphenol (0.74 g, 6.0 mmol) and 4-bromophenyl isothiocyanate (1.28 g, 6.0 mmol) in tetrahydrofuran (20 mL) was stirred for 16 h. The reaction was cooled (0° C.), and LiOH.H2O (0.521 g, 12.41 mmol) was added, followed by the dropwise addition of 30% H2O2 (3.41 mL, 31.0 mmol) over 15 minutes. The reaction was warmed to room temperature and stirred for 16 h. The reaction was then quenched by the addition of 20% aqueous sodium sulfite solution (50 mL) and ethyl acetate (75 mL). The layers were separated, and the aqueous was extracted with additional ethyl acetate (2×75 mL). The combined organics were dried with anhydrous Na2SO4, filtered and concentrated under reduced pressure. The residue was purified by chromatography on SiO2 gel, eluting with 25% ethyl acetate in hexane, to give the title compound. MS (ESI) m/z 303[M+H]+. was added The reaction was then quenched by the addition of 20% aqueous sodium sulfite solution (50 mL) and ethyl acetate (75 mL) The layers were separated the aqueous was extracted with additional ethyl acetate (2×75 mL) The combined organics were dried with anhydrous Na2SO4 filtered concentrated under reduced pressure The residue was purified by chromatography on SiO2 gel eluting with 25% ethyl acetate in hexane
