実験手順
A 2 L flask equipped with a stir bar was charged with DMSO (800 mL), K2CO3 (161 g, 1.6 mol) and 4-methoxy-2-fluoro-1-nitrobenzene (100 g, 0.58 mol). Mono-N-Boc-1,2-diaminoethane (94 g, 0.55 mol) was added to the reaction mixture and stirred for 12 h at 60° C. The reaction mixture was triturated with ice cold water (1.2 L) and the resulting yellow precipitate was collected by vacuum filtration. The precipitate was washed several times with water (5×1 L) and dried on a high vacuum for 48 h to give the desired product as a bright yellow solid (178 g, 98%.)
