The aniline derivative 332, prepared from 2-fluoro-6-nitrotoluene, was transformed through successive reactions as shown in Scheme 60 to give the functionalized indole 333. It was then reduced with LiAlH4 to the dimethylaminopropyl derivative which was quaternized with Mel to the trimethyl ammonium salt 334. Subsequent cyclization and functionalization afforded the pyrroloquinoline 335. The latter could be transformed to the tetracyclic acid 336 (90JHC2151). (Scheme 60)... 

The PE spectra of several substituted nitrobenzenes like the nitrotoluenes, fluoro-nitrobenzenes and dinitrobenzenes have been investigated141. Some data are summarized in Table 18. For the characteristic IPs of the nitro group ( o+, 2) one or two...

When pure explosives are analyzed, a small aliquot of the sample is diluted with ethyl acetate, and identification is based upon the comparison of relative retention times with those of explosives in a standard solution analyzed both before and after the sample. The standard solution is prepared by the dilution of the 11 most common explosives (EGDN, NG, PETN, RDX, 2,4-2,6-3,4 DNT, TNT, o, m, and p nitrotoluene) in ethyl acetate. Also, a mixture of two retention references markers is coinjected with every sample and standard solution, and retention times are measured relative to these substances. The markers commonly used to provide reference peaks in GC analyses are 2 fluoro-5-nitrotoluene (FNT) and 2,6 dinitro-3,4,5-trimethyl-ferr-butylbenzene (MT).
