Reaction Steps
To a solution of 5-nitroisophtalic acid monoethyl ester (80 g) in DCM (700 ml) at 25° C. was added 2M oxalyl chloride solution in DCM (63 ml), and DMF (5 ml). The reaction was stirred for 2 h and then concentrated in vacuum. The residue was triturated with toluene and again concentrated in vacuum leaving the title compound (60 g). Rt=1.40 min for derivatised methylester (method D).
