Procedure

2-Ethyl-9-nitroanthracene (2.55 g; 0.01 mole) (See Example 1) was dissolved in acetic acid (20 ml). To the clear solution at 50° C., there was slowly added tin (II) chloride (9.6 g; 0.051 mole) in concentrated HCl (25 ml). The solution was stirred at 50° C. for 15 minutes and allowed to cool to room temperature. The yellow solid which precipitated was filtered off, washed with water and then neutralised with 10% NaOH solution. The amino derivative was thoroughly washed with water, dried in air overnight and then under vacuo at 50° C. for 5 hours. Yield 1.98 g (88%). The product became brown in colour and was slightly sticky.
