反応手順
To a suspension of tert-butyl (3-aminophenyl)carbamate (7.59 g, 36.40 mmol), K2CO3 (10.06 g, 72.80 mmol) and NaI (16.37 g, 109.20 mmol) in DMF (300 mL) was added 2,2′-dichlorodiethyl ether (5.73 g, 40.1 mmol) slowly at 150° C. under N2. The reaction mixture was stirred at 150° C. overnight, then cooled to rt, poured into water (700 mL) and extracted with CH2Cl2 (200 mL×3). The combined organic phases were washed with water (200 mL×3) and brine (200 mL), dried over anhydrous Na2SO4 and concentrated in vacuo. The residue was purified by a silica gel column chromatography (PE/EtOAc (V/V)=4:1) to give the title compound as a yellow solid (5.91 g, 58%).
