1, 4-diamino -2, 5- […] (1, 4-diamino-2, 5-dimethoxybenzene) (16.9mmol) and 30 parts by weight of diethyl ether (70 ml) at -78 C 1.55N of agitating n-BuLi (16.8mmol) in 11 ml of hexane of. input additional are mixed together. 1.5 in the maintaining -78 C mixture adaptation stirring time. Dichloro d methyl thread column (8.4mmol) and 30 parts by weight of diethyl ether in the -78 C a 2 ml is closed after charging additional adaptation stirring during night at room temperature. After 1.5 reflux time was are input, in water and and stirring. possibility layer hexane and water extraction of water and balancer in a washing machine after the washing phosphorous in the magnesium sulfate expresses water after to remove, is every. D-1 compounds via fractional distillation (45% yield) is obtained.

The synthetic route of 2674-34-2 has been constantly updated, and we look forward to future research findings.
