摘要：
A method of producing a compound formula (I)
the method comprising: reacting a compound of formula (II)
with a compound of formula (III)
wherein,
R3 is hydrogen or halogen;
R1 and R2 are each independently C1-C6alkoxy, or R1 and R2 together are ═O or —OCH2CH2O— or —OCH2CH2CH2O—; and
optionally whereby the reaction is carried out in the presence of an oxidizer.
