Reaction Steps
1,2-Dichloro-4-methyl-5-nitrobenzene (R.J. De Lang, et al. Tetrahedron (1998), 54(12), 2953-2966.) (1 g; 4.8 mmol), morpholine (1 ml) and 1,2-diethoxyethane (1 ml) were heated in a microwave oven at 160° C. for 2 h. The reaction mixture was poured on water/2N HCl 10/1 (50 ml) and extracted with TBME three times. The combined organic phases were dried over Na2SO4, evaporated and recrystallised from hot TBME to yield the title compound as yellow crystals (670 mg; 54%).
