実験手順
In a similar manner, 2,4,6-triamino-5-chloroquinazoline can be reacted with 3,4,5-trimethoxybenzaldehyde and hydrogen in the presence of Raney nickel in 2-ethoxyethanol, affording the corresponding 2,4-diamino-6-[(3,4,5-trimethoxyphenylmethyl)imino]quinazoline. Step C of Example 15 describes in detail the preparation of this compound. In a similar manner there may also be prepared 2,4-diamino-6-(substituted-aminomethyl)quinazolines.
