Reaction Steps

To a stirred solution of 6-amino-m-cresol (5 g, 40.6 mmol) in DCM (100 mL) was added di-tert-butyl carbonate (9.4 ml, 40.6 mmol), under an argon atmosphere. The resulting mixture was stirred for 18 h at RT, quenched by addition of a saturated aqueous solution of NaHCO3 and extracted with DCM. The organic phase was washed with a saturated aqueous solution of NaHCO3, dried (Na2SO4), filtered and concentrated to afford 9.1 g of the title compound as a black oil which was used as a crude material. HPLC: LtRet=4.86 min; LC-MS: m/z 224.3 [M+H]+.
