Example 26

[Figure (not displayed)]

To 146 parts of methylene chloride, 5.0 parts of the compound of the formula [57-2] were added, and the mixture was stirred. Subsequently, 3.9 parts of cinnamoyl chloride (manufactured by Tokyo Chemical Industry Co., Ltd.) were added dropwise thereto at room temperature, then 2.3 parts of triethylamine (manufactured by Tokyo Chemical Industry Co., Ltd.) were added dropwise thereto at the same temperature as above, and the mixture was stirred for 1 hour. After the completion of the reaction, deposits were filtered off, and n-hexane was added to the filtrate. The resulting yellow oil substance was isolated, and ethyl acetate was added thereto. The resulting white solid was filtered off, washed with water, and dried in vacuum to obtain compound 128 as a white solid (1.5 parts).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
