[0057]

[0058] An equivalent amount of 3,4-diaminotoluene in chloroform was added dropwise to 1.0 g of compound 1 (3.17 mmol) in chloroform, and stirred at room temperature for 8 hours. The reaction solution was concentrated and separated by column chromatography to obtain 0.9 g of a white solid with one point in TLC, and the yield was 70%. However, the mixture of compounds 3 and 4 was identified by proton nuclear magnetic resonance, and the ratio was compound 3:compound 4 (or compound 4:compound 3)=6:1. It cannot be determined whether compound 3 or compound 4 has the larger amount.
