Reaction Conditions

Reaction Steps

To a solution of 4-fluoro-2-(methyloxy)-1-nitrobenzene (1.0 g, 5.85 mmol) in 15 mL of DMSO was added 1-methylhexahydro-1H-1,4-diazepine (0.8 mL, 6.42 mmol) and potassium carbonate (2.4 g, 17.4 mmol). The reaction mixture was heated at 80° C. for 16 h at which time the reaction was diluted with ethyl acetate and washed with a saturated solution of sodium bicarbonate, water and a saturated sodium chloride solution, dried over Na2SO4 and filtered. Solvents were removed under reduced pressure to give 1-methyl-4-[3-(methyloxy)-4-nitrophenyl]hexahydro-1H-1,4-diazepine (1.77 g, 6.67 mmol) as a yellow solid containing residual DMSO.
