Heteromine C previously isolated from a Taipei folk medicine plant, has been synthesised for the first time by selective methylation reactions starting from guanine. Thermal rearrangement to 1-methylherbipoline takes place when heteromine C is heated. It is shown that treatment of O6,9- dimethylguanine with methyl iodide gives the O6,7,9-trimethylguaninium iodide with complete selectivity, while similar reaction on O6,7- dimethylguanine results in methylation both in the 3- and 9-position.
