The title compounds were prepared by addition of Grignard reagents to methoxyformamidines 6 and 8 in ether at room temperature. Hydrolysis gives the free secondary amines, or in cases of volatile products, their thiourea derivatives.
通过加入格利雅试剂methoxyformamidines的制备标题化合物6和8在乙醚中在室温下。水解产生游离的仲胺,或在挥发性产物的情况下,产生其硫脲衍生物。
