Steps:

15.A A.

A. Methyl 3,5-Dinitro-4-Hydroxybenzoate 3,5-dinitro-4-hydroxybenzoic acid (4.56 g 20 mmole) was taken up in thionyl chloride (40 ml) and refluxed for 4 hours. The thionyl chloride was then removed by distillation under reduced pressure to give the crude acid chloride which was used without further purification in the next step of the reaction. The crude acid chloride was redissolved in dry methanol (50 ml) and refluxed for 1 hour. The reaction mixture was stored at -20° C. overnight whereupon the solid separated. This solid was filtered, dried and recrystallized from methanol to yield the desired product, 4.00 g (83%), m.p. 110°-115° C.
