Versuchsvorschrift

Synthesis of 2-methyl-9-nitroanthracene ##STR12## Nitration of 2-methylanthracene (Source Aldrich) was carried out using the same procedure as in example 1 to yield the 2-methyl-9-nitroanthracene as a yellow solid. 2-Methylanthracene (2.0 g; 0.010 mole) was suspended in glacial acetic acid (25 ml) and to the stirred solution was added concentrated nitric acid (0.6 ml; 0.014 mole). The solution was stirred in a water bath at 20-25° C. for 4 hours, until the solution became clear. To the clear solution a mixture of conc. HCl and acetic acid (20 ml; 1:1) was added via a dropping funnel over a period of 15 minutes. A yellow solid precipitated out. The solution was stirred for further 30 minutes and filtered under suction. The product was treated by the same method as described in example 1 to give the 2-methyl-9-nitroanthracene as a yellow solid (1.8 g; 73%).
