Disclosed is a process for the production of a compound of formula (ΙΠ). The process comprises a step of reacting a compound of formula (I) with an excess amount of a compound of formula (II) in absence of aromatic solvent:wherein - n is 0 1, 2, 3 or 4; - X is NH, O or S; - each R] group may be the same or different, and is independently selected from the group consisting of hydrogen, hydroxyl, alkoxy, alkyl, carbonyl, carboxyl, carboxylic acid ester groups, amido, cyano, halogenated aliphatic, nitro, or amino groups; - R2 group is selected from the group consisting of hydroxyl, CI, F, Br, amino or alkoxy.
揭示了一种生产化合物的过程,其化学式为(ΙΠ)。该过程包括以下步骤:在缺乏芳香溶剂的情况下,将化学式为(I)的化合物与化学式为(II)的化合物反应,其中- n为0、1、2、3或4;- X为NH、O或S;- 每个R]基团可以相同也可以不同,独立地选自羟基、烷氧基、烷基、酰基、羧基、羧酸酯基、酰胺、氰基、卤代脂肪基、硝基或氨基的群组;- R2基团选自羟基、氯、氟、溴、氨基或烷氧基的群组。
