AMINO--NITROTOLUENE

The formation of 5-nitroindazole from 2-amino-5-nitrotoluene in 72-80% yield is the subject of an Organic Syntheses contribution by Porter and Peterson (1955). [Pg.140]

To a solution of 55 g. (0.36 mole) of 2-amino-5-nitrotoluene (m.p. 129-132°) in 2500 cc. of glacial acetic acid in a 5-I. round-bottomed flask, provided with an efficient mechanical stirrer, is added all at once (Note 1) a solution of 25 g. (0.36 mole) of sodium nitrite in 60 cc. of water. During this addition the temperature is not allowed to rise above 25° (Note 2). After the nitrite solution has been added, stirring is continued for fifteen minutes to complete the diazotization. Any yellow precipitate formed during the next few hours is filtered and discarded (Note 3). [Pg.96]

The third 12-1. portion yields about 20 g. of 2-amino-3-nitro-toluene. The residue in the steam-distillation flask, about 20 g. of crude 2-amino-5-nitrotoluene, solidifies when cooled and may be separated by filtration. It can be recrystallized from 2 1. of hot water, yielding IT-15 g. of yellow plates, m.p. 130-131° (cor.). [Pg.5]

The data on the synthesis of nitrated 2,1-benzisothiazoles are rather scarce in comparison with the corresponding benzisoxazoles. It has been reported that, like other 2-aminotoluenes, 2-amino-4-nitrotoluene reacts with thionyle chloride in xylene to form 6-nitro-2,l-benzisothiazole, whereas 2-amino-5-nitrotoluene does not enter into this reaction (Scheme 2.93) [543],...

Primary aromatic amines react with Caro s acid to form nitroso derivatives, as in the preparation of 5-nitro-2-nitrosotoluene from 2-amino-5-nitrotoluene (71%). ... [Pg.376]
