A facile synthesis of 10-methoxy-4. 8-dinitro-6H-benzo [2,3-c]chromen-6-one
3-Methoxy-5-nitrobenzaldehyde undergoes Knoevenagel reaction with malonic acid to give 3-methoxy-5-nitrocinnamic acid (I). Treatment of I with thionyl chloride yielded 3-chloro-5-methoxy-7-nitrobenzo[b]thiophene-2-carbonyl chloride (II) in 45 % yield. The reaction of II with 2-nitrophenol in benzene...
