Reaction Conditions

Reaction Steps

To a solution of 10-3 (4.36 g, 22 mmol) in dimethylsulfoxide (DMSO; 30 mL) were added morpholine (2.5 g, 1.3 eq) and potassium carbonate (3.98 g, 1.3 eq). The reaction mixture was heated at 80° C. during 1 h, then cooled down to room temperature, poured into 300 mL of water and the resulting yellow solid was filtered off, washed with a bit of water then petroleum ether, to afford 5.8 g (98% yield) of 2-morpholin-4-yl-5-nitro-benzoic acid methyl ester 10-4; m/z=267 (M+H)+.
