USE: Herbicide: especially they can be applied to rice paddy and crop field in low concentration, thus being practical, high-safety and high-selective herbicide.
PREPARATION: A compound of formula II is made to react with a reducing agent such as zinc dust in an organic acid such as galcial acetic acid or an alcohol such as methanol or ethanol at a temperature of 0W120°C to give the compound of formula I. The reduction of the acylated compound gives the compound of formula I in higher yield than that of the compound with H as X.
